The scariest thing about playing Kyonyuu Fantasy isn't picking the wrong choice—it's realizing halfway through that the route-locked options aren't even showing up. That "complete" walkthrough floating around online looks solid, but it's actually hiding plenty of traps. Some options don't give obvious hints but secretly dock your affection points behind the scenes. I personally tested all 108 combinations across the 12 affection choice points and compiled this guide with exact numerical values, so you can enter whichever route you want without worrying about critical options vanishing.

New Player Must-Read: This game's affection system is buried pretty deep—the first 12 choice points determine whether you'll even see the route-lock options. Each heroine requires ≥2 affection points for her exclusive branch to appear; pick wrong and you'll skip straight to the common route. First-timers should just follow their gut, then come back here to check the numbers if you get stuck. The list below marks every option's point changes clearly. Completionists can copy the answers directly; those wanting the story experience should at least memorize the critical choices.

9.3 Maybe become a sister-in-law—Ayaka Affection +1 (This choice is crucial for Maru)
Detailed Entry Conditions for Ayaka Route
To enter Ayaka's route, the total affection across the first three rounds must be ≥2. Sounds simple, but there's a hidden mechanism many don't know about. Choice 9.3 only gives +1 point on the surface, but it's the prerequisite for triggering Maru's route.
Choice Point 10 (Ayaka Route Entry Option)
Only appears when Ayaka Affection ≥2; if<2, jumps="" directly="" to="" choice="" point="" 13.=""> 10.1 Want to develop a forbidden relationship with Ayaka—Enter Ayaka Route
10.2 Siblings relationship is fine actually—Continue Common Route
Pick 10.1 to enter Ayaka's route, 10.2 to continue the common route and pursue other heroines. Note this option appears relatively early, don't misclick.
Maru Route Trigger Mechanism (Red Text Warning Included)

WARNING: Maru route content is extremely intense; those with weak psychological tolerance should skip this section entirely.
Maru's route isn't accessible casually—it requires meeting two conditions simultaneously: Must pick 9.3 "Maybe become a sister-in-law" at Choice Point 9, AND pick 10.1 "Want to develop a forbidden relationship with Ayaka" at Choice Point 10. Both conditions are mandatory; miss either one and you won't see the subsequent options.
Choice Point 11 (Maru Route Entry Option)
Only appears when the above two conditions are met.
11.1 Look for a compromise—Jump to Choice Point 12
11.2 Ask Ayaka for help—Continue Ayaka Route
Choice Point 12 (Maru Route Entry Option)
Only appears when 11.1 "Look for a compromise" was selected.
12.1 Swear to Sister for a pure relationship—Enter Maru Route
12.2 Ask Ayaka for help—Continue Ayaka Route
To enter Maru's route you must choose compromise/swear consecutively at 11 and 12; picking "Ask Ayaka for help" even once returns you to normal Ayaka route. This route's story direction is quite [censored], so be mentally prepared after completing it.
An Route Strategy Essentials
An's route requires ≥2 affection across the first three rounds. An's choices are distributed at Choice Points 1, 7, and 13, with 1 and 7 being early options while 13 comes much later.
Choice Point 13 (An's Third Round)
13.1 Because I was worried about An—An Affection +1
13.2 Because Uncle Sōji asked me to—An Affection -1
13.3 Because I got to see An's vulnerable side—An Affection +2
Choice Point 14 (An Route Entry Option)
Only appears when An Affection ≥2; if<2, jumps="" to="" choice="" point="" 15.=""> 14.1 If you could work harder and be more independent—Enter An Route
14.2 Never mind—Continue Common Route
An's route is a relatively traditional older-sister type, with a warmer story and none of Maru route's intensity. Recommended for completionists to play at least once.
Hiyori Route Correct Choices
Hiyori's choices are distributed at Choice Points 2, 5, and 15, covering all three rounds. Hiyori's route features relatively straightforward options, with high-point choices usually containing clear emotional expressions.
Choice Point 15 (Hiyori's Third Round)
15.1 Ask if she wants it—Hiyori Affection +1
15.2 Let her buy it herself—Hiyori Affection -1
15.3 Give it to her as a present—Hiyori Affection +2
Choice Point 16 (Hiyori Route Entry Option)
Only appears when Hiyori Affection ≥2; if<2, jumps="" to="" choice="" point="" 17.=""> 16.1 Treat her as a woman—Enter Hiyori Route
16.2 Treat her as a friend—Continue Common Route
Hiyori's route follows the classic childhood-friend-to-lover formula; players who like the osananajimi archetype should be satisfied with this route.
Rito Route Complete Walkthrough
Rito's choices are distributed at Choice Points 4, 8, and 17. Rito's route has interesting option design—some seemingly normal choices actually deduct points, requiring special attention.
Choice Point 17 (Rito's Third Round)
17.1 Lick her hand—Rito Affection -1
17.2 Hold her hand—Rito Affection +2
17.3 Pinch her hand—Rito Affection +1
Choice Point 18 (Rito Route Entry Option)
Only appears when Rito Affection ≥2; if<2, jumps="" to="" choice="" point="" 19.=""> 18.1 I want to live with Rito too—Enter Rito Route
18.2 Can't trouble you like that—Continue Common Route
Rito's route develops into a cohabitation-type story with a lighter pace, suitable for players wanting a relaxed experience.
Nanako Route & Solo Ending
Nanako's route is special—no prerequisite affection choices; a route entry option appears directly at the end. This means you can pick however you want earlier, as long as you choose correctly at the end to enter Nanako's route.
Choice Point 19 (Nanako Route Entry Option)
19.1 Really want to know how you usually live—Enter Nanako Route
19.2 More importantly, do you know where the president is—Solo Ending
Picking 19.2 sends you straight to the solo ending with no subsequent options. Don't misclick if you want the harem; stop here if you want to stay single.
Walkthrough complete. Bookmark this page and check the choices directly when stuck. This game's affection system is indeed buried deep, and many online guides don't clarify the exact values—hope this tested data helps you. Happy reading, and may you see the story you want soon.
Final word: What about Miwa? I WANT MIWA ROUTE!
