Isekai Quartet Season 3

A normal school day becomes impossible the moment new faces walk into Class 1. Ains, Kazuma, Subaru, Tanya, and the rest are still stuck in the same tiny «another world» campus, where every problem gets filtered through homeroom rules and chibi logic. This time the roster expands again. Shadow shows up with the quiet confidence of someone used to running a secret organization, and his Shadow Garden followers treat the classroom like a briefing room. Otto and Garfiel also slip into the mix, bringing fresh friction to the already crowded desk rows. The old regulars try to keep their routines intact, but every small event becomes a negotiation over who leads, who refuses to play along, and who accidentally reveals too much about their real life back home. Alliances form and snap over everyday school routines, and the class keeps learning the same thing: even in a harmless setting, pride is a weapon and misunderstandings spread fast.
