LOL no way. Hitomi actually sit in between Nitta and the club girl after she tried to flirt with him in the beginning! Very subtle detail I never noticed till now
Rereading Hinamatsuri and this chapter really propelled up Hitomi's story. Falling for Nitta, finding an adult she can respect (since all the other ones are bums, including her dad), balancing work and school life (showing the sample toy to her friends) and the first time she has been humbled...
Surprising way to celebrate your 100th chapter milestone without the actual main characters. But yeah... her sister is very yandere and manipulative, especially the way she tried to "pretend" kill herself and strike immediately
Well I guess Ain wasn't able to differentiate them as good as he thought. No wonder the angel sister went full yandere, considering this imouto went full yandere as well.
