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.
Speaking of Hihi,
I wonder what he's doing now.
.بالحديث عن هيهي، أتساءل ماذا يفعل الآن
¿Qué estará haciendo Hihi ahora?
¿Qué estará haciendo Hihi ahora?
En parlant de lui,
je me demande ce qu’il fait.
Chissà che starà facendo Hihi a quest'ora?
Falando no Hihi, o que será
que ele está fazendo agora?
Раз уж заговорили за Хихи, 
чем он сейчас занимается?
