Oricon Comic Ranking Summary

5th place: The free life of a leftover person from another world: I'm not a hero, so I'll just do what I want 9

A boy named Shin is caught up in a hero summoning and transported to another world.
After successfully completing the ritual at the Tenrō Festival, he returns to his peaceful life at the academy.

One day, Shin meets a girl named Elicia, a student visiting from the Elvia branch campus on a student exchange program.
Burdened by her appearance and the cultural differences, Elicia struggles to fit in and becomes emotionally withdrawn.

However, after spending time with Shin and his friends—eating vegetables, learning horseback riding—her physical condition begins to improve.
Before long, her skin clears up, her body slims down, and her confidence grows.
With her newfound brightness, Elicia decides to pursue her long-held dream of horseback riding by starting her own club, with Shin’s support.

But things take an unexpected turn when the traditional equestrian club takes notice—
and challenges her to an unreasonable horseback riding duel...!
