I, the world's top killer, have twelve "tenants" living in my head.
There's a seven-year-old who wants to be a pastry chef, a veteran who loves tactical shopping, and a calm analyst who spends his days figuring out how to kill me.
And my latest mission: kill myself.
To be precise, it is to eliminate all "false personalities", including the "I" who is the killer.
Now, not only do I have to deal with the pursuit of external organizations, but I also have to hold a "personality conference" in my mind to debate who controls the body today, and how many pieces of strawberry pie I should buy.
This is a self-inflicted siege against oneself. The only way to survive may be to learn to live in peace with all "I"s.
