Itsuki Kaitou lived a miserable life. When he dies, the divine authorities don't know what to do with his soul, so he gets reincarnated as a loli in another world. What's more, he isn't allowed to keep his memories so he actually believes that now he is and always was a girl. But she does have now powers that you really would call a cheat. Under the name of Ayaka, our mc must follow her heart and her heart is telling her: Live a slow and lazy life. I don't want to work, I just want to have fun and enjoy life. But... certain events will force her... to be active.

Loli MC - check, OP from the start - check, cute girls - check, despite treating the world through the eyes of a child, but manages to keep going because of followers and extreme power - what's not to like about that?
