Sisters' Journey: Black & White World's Colorful Adventure - Complete Illustrated Walkthrough Guide

Rerolling Initial Stats

Like the prequel, your initial choices determine starting attributes, skills, sister affection, and money. You can start casually with your preferred options, or check the tips below. (Used Cheat Engine to check data—took forever to compile)

First, the base stats before selections: Attack, Technique, Defense, Willpower, and Wisdom fluctuate between 4-6, increasing based on three subsequent rounds of choices.

First Choice Layer

Second Choice Layer (Four random scenarios)

Third Choice Layer

Prefixes (Modifiers)

After completing the above selections, your prefixes are determined, appearing as "XX's XX's Brother" (sometimes only one modifier) like the image below.

Partial modifier effects shown below:

New Game+ Inheritance

Recommend doing a second playthrough for easier skill completion.

Game Tutorial

At the start, you can choose Normal or Hard difficulty. Choose Normal for casual play, Hard for a challenge. Hard mode is genuinely difficult. This guide uses Hard mode as an example, so early-game sister interactions are minimal.

Five-Dimensional Stats

Prioritize Attack and Defense upgrades, then Wisdom. Technique and Willpower come last. Skill Points can be used to learn skills.

Skill Recommendations

After accumulating 30 Skill Points, unlock skill learning. The tutorial automatically spends 30 points to learn a special move. Bottom skill learning priority: Cooking Expert → Exploration Expert → Agriculture (learn this before Exploration if weekend is approaching) → Healing Power → Sister Love (only useful for Grand Adventure)

Top-right skills vary based on your choices and prefixes. Top-right skill priority: Battle Genius → Preparation → Leader → Cooperation → Formation Setup → Skill books from Five Instincts Shop. Short-term Battle and Long-term Battle aren't necessary; everything else is worth learning.

Daytime

Wake up daily and do quests at the Guild.

Common quests include:

1. Help at the Shop: AP -25, SP +6, Gold +350g

2. Basic Training: AP -35, Max AP +3, Willpower +6

3. Defense Practice: AP -35, Defense +11, Willpower +3

4. Attack Practice: AP -35, Attack +11, Technique +4

5. Study Session: AP -20, Wisdom +10, SP +6

6. Regional Contribution: Increases Guild Reputation and SP, costs 40 Stamina. Has chance for combat—always save/load to get combat and win. Victory grants Attack +3, Technique +3, Defense +3, SP +12

7. Secret Training: AP -35, Willpower +13

8. Expedition Commission: Similar to Regional Contribution but only costs 20 Stamina. Always do this when available.

Quest Priority: Expedition Commission → Regional Contribution → Defense Practice → Secret Training → Attack Practice → Study Session → Help at Shop → Basic Training

You can train Attack, Technique, and Wisdom at home, so quests prioritize Defense and Willpower.

Companions

During daytime, if your Stamina is above ~80% of max before starting quests, there's a chance to trigger companion story events that boost affection and power while unlocking skills. Control your stamina usage the previous night to ensure you wake up with >80% stamina.

Salary

I modified Don's original chart according to the official Chinese localization. You're welcome to check out Don's page as well.

Evening

Early game, let sister cook. After learning Cooking skill, have brother cook when short on SP; otherwise sister cooks. Can save/load for Great Success. If remaining stamina >60, choose Muscle Training for Study; if<60, choose="" meditation.="" prioritize="" reading="" adventure="" books="">

Click sister for interactions—Intimate Contact, Chat, Tea Time won't be covered here. In Hard mode, sister romance isn't top priority. If short on SP, tell sister horror stories (+2 SP each time, but may scare her—save before telling).

Key point: Bathing. Recommend bathing alone before Trust 100 (do nothing). Trust 100-200: can bathe together for Trust + Lust boost. After Trust 200, bathe together: Wash Body → Chat (any topic) → Wash Body → Lewd Thoughts (repeat 3x to reduce Star Rain)

Physical Condition

Sister sometimes gets sick and lies in bed. Immediately Care for Sister. If this option isn't available, it will appear the next day—must do it or sister's condition worsens leading to game over.

Cooking

Sister cooks: 100g

Great Success: Mood boost (small), AP +25, Max AP +1, Energy +1, Increases Motivation. Takes 30 minutes

Success: AP +20

Brother cooks: 100g

Great Success: Trust +8, Mood improves, AP +20, Motivation increases, SP +3. Takes 1 hour

Success: Trust +2, AP +15, SP +1

Failure: Trust +2, AP +10, Motivation decreases, Willpower +2, SP +2

Eat Out: 300g (unlocks Day 32), Trust +2, Mood improves, AP +20, Motivation increases. Takes 30 minutes

Simple Meal: 50g (when cash<500g), sister="" lust="" -5="">

Study

The dumbbell icon in the bottom-left corner.

Muscle Training adds Attack, Practice Swings add Technique, Meditation adds Wisdom. Study Priority: Muscle → Meditation → Practice Swings

Reading

Bookshelf icon in the bottom-right corner. Can read various books—prioritize Adventure Books (+2 to all five stats, but may fail and be consumed, so save before reading). Other books aren't needed before main story ends; can buy books on weekends.

Family Meeting

Held every Friday night before bed. Can discuss topics to increase/decrease stats. Recommend Dreams Topic until main story ends for Guild Reputation + SP.

After choosing, select next week's lifestyle policy. Lifestyle Priority: Work Life → Physical Training → Reading Week → Healthy Life → Frugal Life (abstinence for one week changes prefix to "Completed") → Others

1. Normal Days: No effect

2. Bento Life: +10 AP after Guild activities

3. Work Life: Shop help reward +50g, work reward +400g (when short on cash)

4. Frugal Life: Meal cost becomes 0g, random activity after dinner (useful for random events)

Unlocks from Day 33:

1. Adult Phase: Lust +2 daily

2. Healthy Life: Sleep AP recovery +10, sleep at 10 PM on Fri/Sat (useful when short on stamina, like during Grand Adventure)

3. Physical Training: Study bonus +1 (when needing to boost stats)

4. Reading Week: Obtain 2-4 Adventure Books + 1-2 H-manga, sleep at midnight on weekdays (when needing to stay up late)

Unlocks from Day 61:

2. Debauched Life: Sister Star Rain +20 daily

3. Luxury Phase: Meal cost becomes 200g, Trust +2, AP +10, Energy +1

4. Full-on Troubles: Lust +10% daily, increases "Little Bird Flutter" effect

5. Abstinence Life: Achieved by not having sex until next Family Meeting. SP +20 (useful for prefix changes)

First completion: First XX in "XX's XX's Brother" becomes "Successful"

Second completion: Second XX becomes "Cool"

Third completion: First XX becomes "Forbidden XX"

Fourth+ completions: Toggle between "Successful" and "Forbidden XX"

Sleeping

Ensure next day's stamina exceeds 80% before sleeping, keep Star Rain below 50 or you'll wake up mid-night with reduced recovery (sometimes doesn't apply). Normal sleep recovers 30 stamina, 50 with down duvet. Sleeping early on Fri/Sat nights can trigger sister development.

Weekend

Early game: Work, Self-Training → Running

Mid game: Grand Adventure, Super Grand Adventure

Post-main story: Let's Expedition!, Self-Training → Any

Main Story Flow

Day 11: Exchange battle vs Gourmet Club (basically PCR's Food Hall). Almost guaranteed loss.

Day 18: Exchange battle vs Running Radish Hobby Club. Generally: Kanai attacks 3x, brother uses special move, then Kanai and brother normal attack to win. After battle, fight Dawn (win/loss branches into two routes). (Hard mode first playthrough is basically guaranteed loss; only winnable in New Game+). Should earn ~10,000 profit this week.

Day 21: Go shopping, buy dumbbells and iron geta, buy 10 Adventure Books at bookstore. Should trigger Kasumi's story (IMPORTANT). After buying enough gifts to reach 100 Trust, unlock bathing together. Buy 1-2 skill books if you have extra cash.

New Menu Operation (Dawn battle loss route) Day 25: Have sister cook dinner (best to do several days). After triggering New Menu Operation, sister develops new menu after Guild activities—triggers multiple story events.

Seal Extermination Operation (Dawn battle victory route) Day 25: Strength Test (Yukari)

Win → Transfer to Seal Extermination Operation, Lose → Transfer to New Menu Operation

Day 29: Triggers Expedition Commission (3-day limit). When seal extermination count reaches 10/10 or progress reaches 40/40, Seal Couple Battle ※ Trust +5, AP -20, Guild Reputation increases, all stats +8, SP +12~

Day 39: Triggers Kasumi's story

Day 42: Manga Merchant Day—buy books, trigger Kasumi's story. Buy discounted skill books first, then sleep pillow and down duvet if you have cash left, and more Adventure Books (weekends after this can focus on Grand/Super Grand Adventure)

Day 43: Kasumi joins party

Day 46: Eight Societies battle vs Giant Brothers. Opponent alternates Defense/Attack—respond accordingly.

Day 53: Eight Societies rematch vs Gourmet Club. Recommended sequence: Kanai normal attack → Kasumi uses skill → MC uses special → Kasumi uses skill → MC uses special → MC normal attack to end.

Days 57-61: Training camp. Ensure sleep can fully recover stamina on Day 56, max out condition.

Boost Attack Power (+Attack & Technique), Boost Defense (+Defense & Willpower), Boost Skill Power (+Wisdom & SP), Boost Vitality (+Stamina & Condition)

Days 64-67: Do Expedition Commission daily and complete it.

Day 70: Go shopping, buy 10 Adventure Books and other items

Day 74: Eight Societies finals vs Scout Alliance. Guard for 5 turns then it's easy, or just brute force.

Day 78: Eight Societies semifinals vs Seven Star Agency. Quick victory—drags out and opponents get attack buffs making it hard.

Day 84: Eight Societies finals vs Dawn. Survive 3 turns to fight Shadow, finals interrupted.

Days 85-99: Do Expedition quests. After expedition quests end, boss battle begins. Fight Shadow then Black Hole. In Black Hole battle, keep guarding—heal with Yui's skill when low on HP. By turn 10, buffs stack up—use special move then finish.

Day 100: Main story ends. If you completed Grand Adventure, Dawn exchange battle triggers 3 days later—win to trigger ending.

After Day 101: Weekday daytime options locked. Weekends unlock "Let's Expedition!" Defeat Squid King in expedition to get tentacle for nighttime items. If Kasumi hasn't joined, weekend bookstore visits trigger her recruitment story.

Day 106 (after ending triggers): Hot spring story unlocks. Weekend hot spring battle vs Monkey Triple Battle (just survive until turns end, winning not required). After hot spring story, weekend hot spring visits unlock, five-dimensional stat caps raise to 500, weekday quests reopen, Monkey King Expedition Commission Day 999.

Endings & Battle Position Unlocks

Doggy Style: Unlocked by reading H-manga → Unlocks corresponding nighttime position

Deep Mountain Position (Piledriver): Help sister wipe body twice (when sister is sick: Bath → Help Sister Wipe Body); After Grand Adventure clear: Reach 120 Star Rain without release and battle 2-3 times → Unlocks corresponding nighttime position

Six-Nine Position: Blowjob → Next day after mouth ejaculation, sister unlocks at midnight

Cowgirl Position: H-manga found by sister. Ignore her when sister Star Rain >80, next morning triggers either missionary or cowgirl (post-defloration)

Anal: Read H-doujinshi → Unlocks optional bath position

Lust 50+: Can touch butt (outside)

Lust 75+: Unlocks doggy style

Lust 100+: Dialogue changes, can touch butt (inside), can use massage stick (if not virgin)

Lust 150+: Adds wake-up commands, can use vibrator (requires development), unlocks drinking

Lust 200+: Dialogue changes, unlocks anal (requires development), tentacle becomes usable (if non-virgin)

Sister's Star Rain is important. GOOD bar increase relies on sister's Star Rain and excitement level. Low Star Rain makes sister angry in morning, so use Star Harassment to raise it beforehand.

When Lust is low, some actions are restricted by GOOD bar. Rough thresholds: Touch there (outside) 20%, Insert 50%, Touch there (inside) 80%. These restrictions disappear when Lust increases.

Since insertion requires 50%+ Star Rain, and H reduces Star Rain, you need to restore it with caresses before inserting again.

When GOOD bar is high, sister will ask to continue if you try to end H. Ignoring her reduces mood but increases Star Rain. To satisfy her, continue until sister climaxes, GOOD bar drops, then end.

Anal-related: With Lust 100+, fingers can enter. As Technique improves through repeated caresses, sister's dialogue changes with development level. Inserting vibrator while she sleeps can rapidly develop, but her reactions change based on anal development level—slow development is possible if you want different reactions.

Warning: Sister's Physical Condition - Making sister climax worsens her condition. Especially vulnerable before Grand Adventure clear—too many climaxes (dozens) and she'll die next day. Be careful not to overdo it. After Grand Adventure clear, dozens of climaxes won't kill her.
