While Kenji already has his own route (kind of), this is my series of ideas if the route was not cut short by Hisao's death.
So basically, somewhere there's an extra decision that will cause Hisao to not back off during the roof scene and fucking die. I don't know when the decision would be or what it would be, but it would have that effect. Hisao does not back away as Kenji drunkenly leans forwards, and the twom share an accidental kiss. Hisao is shocked, but before he can do anything Kenji pulls away. Hisao realizes that Kenji's so drunk he'll probably never remember it, and tries to forget it ever happened. By the night's end, Kenji is so drunk that Hisao has to walk him back to his dorm. The last thing Kenji says before going inside is "Dude... *hiccup* I love you, man... in a manly way... like bros." Hisao just closes the door and goes off to his own room, trying to forget everything that happened.
The next morning, Hisao has a hangover, and tries to manage it by taking a shower. Just then, Kenji stumbles in the bathroom in excruciating pain. He drank way more than Hisao, and as such his hangover is far more extreme. He's not handling it very well, and screeches for Hisao to help him (By the way, Kenji is fully dressed in this scene). Hisao, because he's in the shower and is not thinking clearly, is unaware what is wrong with Kenji, and gets out of the shower quickly, covering himself with a towel. He panickdely asks Kenji what's wrong, and when he reveal it Hisao just yells at him for overreacting. Kenji just rubs his forehead, still in pain. He says "I don't want to deal with this shit right now, just help a man out!"
Hisao, unsure what to do for him, agrees to help him even though he has no idea what he's in for. Kenji tries to usher Hisao out of the bathroom while he's still in a towel, but he obviously refuses and then gets dressed. Kenji invites Hisao in his dorm, which is a mess of bizarre contraptions Kenji has built to "defend himself from the Feminists." They're mostly just messes of wire and metal, but some of them function properly. Kenji appears to have created some working machines. Hisao comments that Kenji could probably get a degree in programming or robotics or something, but Kenji dismisses this, saying he wants to enlist in the army to thwart the feminists. At this point, Hisao begins to seriously worry for Kenji. He has such a brilliant mind and has even built a few working machines, but he's ruining his life with his rambling on about feminists and whatnot.
Anyway, I don't feel like updating this right now. I want to go play the game, I'll continue this series of ideas later.
