The Quintessential Quintuplets manga volume 8 features story and art by Negi Haruba.

Having laid everything on the line with Futaro, Nino is left to wait for a response to her confession of love. Meanwhile, a surprise trip for both the Uesugis and the Nakanos to a local inn has Futaro facing tests even he can’t prepare for—trying to figure out mysterious new characters, conflicts between the quints, and a new spin on the Quintuplets Game. As relationships new and old reveal themselves, the quints’ increasingly overbearing father looms over all, and Futaro must come to terms with his own concerns about losing his job and relationship with the quints.
