The Double Agent Never Surrenders

This story was written quite a while ago and contains *English-language characters. Please turn off automatic purchases and skip those parts directly! If that bothers you, please don't read!

Suddenly kidnapped by an unknown System and taken to another world, Onikiri refuses to just sit around and wait. He wants to return to that cherry-blossom garden.

Higekiri: Maybe you could come with me. My family has a huge cherry-blossom garden too.

*

System: Your mission is to help this world's Seimei clear away obstacles and eliminate the future second-generation head of the Nura Clan!

A double agent never gives up!

Onikiri: Sorry, I'm confused. I turned around and stabbed the nine-tailed fox to death.

*

System: You failed all your missions. Accept your punishment!

Onikiri: What did you say?

Higekiri: Ignore him. His lair's already been taken over, and he's still putting on a show?

Onikiri: So what should I do?

Higekiri: See that man in the brown coat, with bandages wrapped around his hands? Let's go stab him.

Dazai: ???

A double agent never sets up a good person!

Dazai: Then...

Nakajima: You're not a person.
