A certain Master Shishen was dragged along by a friend to cosplay, but ended up transmigrating the moment they stepped outside. [Yes, it's that old-fashioned.] And the world they ended up in wasn't even Touken Ranbu!
The Master Shishen is forced to cosplay sword-wielding Tsukumogami in one world after another, until they can never go back again~
First world: Tsurune: Kazemai High School's Kyudo Club (Mikazuki Munechika)
Minato Narumiya: Masa-san??? Huh? Why is there another Masa-san here?
Masaki Takigawa: The one on the left is Mikazuki Munechika. I'm on the right, Minato.
Mikazuki Munechika: Hahaha, did Narumiya mistake us?
Second world: The Yakuza's Guide to Babysitting
Third world: Natsume's Book of Friends
Theme: Can you hold on to who you are?
