One Punch Man Manga Chapter 120

Genos leads the support team and Waganma to safety, clearing monsters along their path. Sekingar updates Sitch about Waganma’s rescue. Learning from Sekingar that Saitama is already inside the Monster Association (via Nyan’s intel relayed by Drive Knight), Genos declines further Hero Association orders and storms the Monster Association hideout, leaving Waganma in Food Battler Futoshi’s care. Sekingar also provides Genos with Drive Knight’s reconnaissance data.
