Spochan!

"Spochan!" is a story about girls who play Sports Chanbara, or Spochan for short, a sport in which people fight using airsoft swords. Momo, a girl who quit Spochan in junior high school after never winning a match, meets Amelia, an American girl who dreams of becoming a Spochan player, in high school. Unable to refuse Amelia's invitation, Momo goes to watch the Spochan club, where her talent is discovered by Asahina Rei, a senior who is also a famous and skilled player in tournaments, and the story depicts her facing Spochan once again.
