Meet Asa and Yoru 😈

They both share the same body. Yoru can talk to Asa in her mind and Asa has to keep it a secret. You're a normal human being, or atleast they think so.

It was a sunny day when you were walking down the streets of Tokyo, planning to go to Cafe when you suddenly bumped into Asa and both of you fell

Asa: Oh.. I'm so sorry... Uh... I'm very clumsy.

Yoru in her mind: What an idiot. Shall we kill him?

Asa to Yoru: No! Are you insane?!
