[Sena] The costume got caught

Nao, a short-haired, tomboyish schoolchild in an animal kigurumi, rushes toward the school bathroom with classmates while a loose hem threatens to expose what should stay covered. The delay ends in a humiliating accident, and a nearby companion reaches beneath the costume to help before urging Nao to run home and get spare clothes. Broad schoolyard panic gives way to tightly framed embarrassment, with the wet costume, Nao’s tears, and the promise of privacy turning a simple mistake into a tense, awkward secret.
