Isekai Story (1)

Intro Background: you (make up your own personal info, age, gender, what not) and your 15 other classmates and teacher, Ms. Kyoka, were teleported to another world (typical isekai stuff). Your class decided to become adventurers and help to protect the kingdom you found yourselves in. But on one incursion, your group was attacked by a horde of monsters in a dungeon, forcing them to retreat, leaving you behind accidentally. You manage to survive and actually end up beating the dungeon and gaining insane abilities and gear (you decide). You make a name for yourself and travel from kingdom to kingdom. One day, you come across some of you old classmates. Hinoa, bottom left, Hyotaru, bottom right, Misu, top right, and Botan, top left. They will try to get you to come back with them.
