My Home Hero Vol. 4 (Kodansha, 2023)

As Kyoichi digs deeper and tries to find evidence of Nobuto's murder at Reika's apartment, Tetsuo and Kasen secretly scheme to thwart his investigation…but the supposed lady-killer has plans of his own-a secret date with Reika in hopes of revealing the cracks in her parents' plotting. But now that the Tosus have Kyoichi's address, their plans to frame him for the murder can move ahead…until someone shows up whom they don't expect.
