Brother x Sister

The first things to enter Seiji’s line of sight were Shika’s planned titles for her books.

There was Haru-Kagu Story, Disqualified from Being Siblings, I am the Younger Sister, Story of a Brother, and so on…

Seiji was rendered speechless by these titles!

He detected an overpowering aura of bro-con just from the titles!

Haru-Kagu Story was just a combination of their last names, Haruta and Kagura!

Disqualified from Being Siblings was basically the same as Osamu Dazai’s No Longer Human, which could literally be translated as "Disqualified from Being Human!" Or was this going to be this world’s version of Disqualified from ___? Perhaps it was plagiarized… no, an imitation.

Was I am the Younger Sister supposed to be an imitation of I am a Cat, or something similar?
