Shuu Tsukiyama (Book 2): Talk Yandere To Me

This is book two as it says in the title. I advise you to read that before this one. (Y/n) went back to her old life she had before the battle of the 11th ward. But things still weren't the same. Tsukiyama being one of them. But when a men interact with her, they start to die off. She's unsure what to think or make of the situation. Her lust and love for Tsukiyama stands in her way, but after finding out Shuu's the one who's been doing it all along. Will her feelings for him increase in something more? Or will something else stand in their way of her doing so?

(Really bad at descriptions.)
