Back in modern time, Itsuki celebrates his book becoming an anime and has a mixer at his apartment. Haruto brings over a board game about being a light novel artist and they all play. What kind of results will they all get in the end?
After all, I don't have a little sister.
Denn ich habe keine Imouto.
Después de todo, no tengo una hermanita.
A fin de cuentas,
no tengo una hermanita.
Et ce, parce que je n’ai pas
de petite sœur !
Dopotutto, non ce l'ho davvero una sorellina.
Afinal de contas, eu não
tenho uma irmã mais nova.
Ведь сестры младшей
у меня нет.
