So here’s a topic that spurred off of a discussion with @daysofsummer and @kyuketsukimiyu on Twitter…
Excluding Nagisa, which girl do you think suits Tomoya the best?
It’s as good a point as ever to discuss, since the bookclub is now past the point where we’ve covered all the female routes except for Nagisa’s. Why exclude Nagisa? Because she is objectively best girl for Tomoya (fite me)
As for my analysis… I might have to do a process of elimination on this one. First let’s take out the obvious: Fuko shouldn’t be in a relationship with Tomoya and the romantic ending is a joke. She’s fun to bully, but her personality clashes too much with Tomoya to even make that something worth considering.
Ryou doesn’t have much of a chemistry with Tomoya either. Sure, she does get her ending with him, but it feels like Tomoya was just going with the flow and that sort of relationship would have fallen apart in the long run, I wager.
It’s a bit hard to push him with Mei at this point because of the age gap, and while it isn’t that much of a gap to matter in the long run, Mei still has a lot of growing up to do in the meantime.
Kotomi seems like a good choice at first: she genuinely causes Tomoya to grow as a person. However, that attitude also has one flaw: Tomoya himself is flawed, and has his own set of problems, none of which are worth scoffing at. I just feel that Kotomi lacks the social awareness to be able to help support Tomoya in handling his problems, once he needs to confront them. While that may not negatively affect Tomoya’s relationship with Kotomi, it would definitely keep him at a standstill, and that wouldn’t be good for Tomoya either.
Then we go over to Tomoyo, who may seem the exact opposite of Kotomi in that regard. However, she is pretty pushy, especially with things that she thinks is right. Tomoya, on the other hand, is very very stubborn about his problems. Once Tomoyo decides that Tomoya needs to face his problems head-on, she will push him to do it. That can only end up with Tomoya’s stubbornness causing him to walk out, both from his problems and from Tomoyo.
Misae feels a lot like an older sister to Tomoya, frankly. However, it would end up a bit too much, as it would cause Tomoya to be reliant on her in many situations, much like the majority of the dorm boys are reliant on her. Misae also has leftover emotional baggage that seems as if it would be impossible to heal, should Tomoya had pursued a relationship with her.
Which leaves us with… Yukine and Kyou. The chemistry between Yukine and Tomoya definitely felt natural, as it did with Kyou. Tomoya definitely has the guts as well to handle Yukine’s posse, so that shouldn’t pose much of a problem either. Kyou might be pushy in the same way Tomoyo is, but she knows when to stop early enough to to prevent Tomoya’s stubbornness to take over. When that happens, I think that she’d actually be more understanding than any of the other girls.
It’s definitely a close call between the two but I’m gonna have to give it to Kyou. She’s known Tomoya for a longer time and can deal with him when he needs to be dealt with. Whereas, while Yukine’s overly-accommodating personality works with Tomoya for the most part, there might be times where he just needs that sort of push to be a better person.
Delving heavily into After Story territory here, but it has always been a headcanon of mine that, in some alternate universe, Ushio doesn’t die and Tomoya learns to get over Nagisa’s death and finds in Kyou a good wife and potentially a good mother for Ushio. Well, at the end of the day, it’s still just a headcanon and shall remain inside my head
