Jitsu wa Imōto Deshita. - Saikin Dekita Giri no Otōto no Kyorikan ga Yatara Chikai Wake #4

Jitsu wa Imōto Deshita. - Saikin Dekita Giri no Otōto no Kyorikan ga Yatara Chikai Wake is a light novel series written by Shirai Murakami and illustrated by the artist known as Riko Korie. The fourth volume, released as part of the ongoing series, continues the narrative focusing on the evolving and often complicated domestic dynamics between step-siblings. The series belongs to the modern 'rom-com' genre popular in Japanese light novel publishing, characterized by its focus on character-driven interactions within a shared living space.

The visual identity of the series is heavily defined by Riko Korie's character designs, which emphasize expressive, soft-toned aesthetics typical of contemporary seinen and shonen light novel imprints. Volume four maintains the consistent stylistic direction established in earlier installments, aiming to balance emotional character development with the series' established tone. Upon release, it was received primarily by the dedicated light novel audience, serving as an expected continuation for readers invested in the specific romantic tensions developed throughout the preceding volumes.
