Moe War is a comedic oneshot within which a popular girl tries to act "moe" to get out of repaying an otaku. As she soon realizes, however, she doesn't understand moe at all.

Mizuno Kaori attends an all-girls high school and likes to spend time with her friends after class playing soccer. They'd like to create a club, but they're one member short of creating a team and people think it's foolish for girls to play soccer. Studying at the same high school, Umezawa Hikari is very popular among the boys but doesn't talk much. What most people don't know is that she plays soccer pretty well and dreams of becoming a national player competing in the World Cup. She then joins Kaori's group with plans to challenge a boy's soccer team from another high school. If they can defeat the boy's team, then they can let people know that they really mean business and this will also serve as a small step towards her dream.
