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.
If the world is that sad,
then I'm done with it.
،إن كان العالم مملًا هكذا
.فقد اكتفيت منه
Wenn die Welt echt so geworden ist,
habe ich genug.
No quiero vivir en un 
mundo tan aburrido.
No quiero vivir en un
mundo tan aburrido.
Si le monde est si fade,
je n’ai plus rien à y faire.
Se il mondo è tanto insignificante, 
basta così per me...
Se o mundo é triste assim,
acho que eu não quero mais.
Если мир настолько грустный, 
тогда мне нечего здесь делать.
