This feels so contrived. Like, massive jumps in thought to make the facts fit the story and not the other way around.
True, but I think it's supposed to and is written that way. Like everything so far is just conjecture from the mystery obsessed. The initial jump from neglected child to "house for trained child assassin" was already a huge jump. I feel like these wild assumptions are meant to throw off the trail about other theories.
Also, I think the artist purposely designed the MC as androgynous reflecting on the original author, Uketsu.
