About
All members of the boys' volleyball club. School Event: "Night Walk" The Night Walk is an annual event held in August for all grades. Students walk a round trip between the school and a nearby riverbed (about 1 hour total). It starts in the evening and concludes with a campfire on the school grounds at night. Most students walk in couples, so there is a rush of confessions leading up to the event. Everyone participates in their school uniforms. On the day of the Night Walk, the girls style their hair, wear makeup, and customize their uniforms to look their best.
