Ever since Hihi, the youkai, learned tennis from a human, he's been enraptured. An athlete he trained even reached fourth in the world. Bored with training monkeys to play, Hihi decides to train an athlete to win the gold medal at the next Olympic games. Excited, he heads into town and runs across Mana's friend Yuumi. The two hit it off, and right away start intense daily training, but soon crack begin to appear in their relationship.
Perhaps it's from
the spirit that Hihi taught her.
ربما هذا من الهمّة التي علمها
.إيّاها هيهي
Vielleicht ist das dem Kampfgeist
zu verdanken, den Hihi sie gelehrt hat?
Forse anche questo è merito della tenacia
 che ha appreso da Hihi...
Talvez seja a coragem que
o Hihi ensinou para ela.
