In the upcoming October chapter, the curtains will draw to a close for Takehito Moriizumi’s enthralling manga “Sasasa Nana no Kyūmei” (Nana Sasasa’s Investigation), as revealed in the September edition of Shogakukan’s Big Comic Original Zōkan magazine.

At the heart of the manga lies the tale of Ruru Sasasa, a college student, and her enigmatic sister, Nana Sasasa, a renowned mystery novelist. The sisters are grappling with a recent familial loss—the passing of their uncle merely a month ago.
A poignant opportunity arises when Ruru decides to explore their uncle’s former residence. Amid the artifacts of time, a faded photograph of Avi, their uncle’s long-lost partner, surfaces, becoming the key to unlocking a trove of buried memories within Ruru’s mind.
