I Got Caught Up In a Hero Summons, but the Other World was at Peace! (Manga) Vol. 9

CHRO MAKES HER MOVE! Chro and Kaito visit Lilia's residence to discuss profits from Kaito’s magical calculator! Meanwhile, Kaito's sleepover date with Isis leaves him determined to learn more about the realms he traverses. But the sleepover leads a jealous Chro to surprise Kaito by getting much closer to him...literally! Series Overview: Miyama Kaito is no hero. He’s just a normal university student who gets caught up in a hero summons with an actual Hero. But even “Hero” is just a ceremonial role these days, ever since the Demon Lord was killed centuries ago. In a world where demons are chill, nobles are no longer corrupt, wars are a distant memory and there are no more epic quests to complete, what’s a regular guy to do? Why, build a harem, of course!
