Left- Cocchi Right- Chi
Cocchi is a stray kitten much like Chi. He looks like a male version of her. He was one of 2 kittens in a box two boys found. The boys took the other kitten and he got abandoned and became a stray .He appears in vol.6 and named in vol.7. He sometimes will play with Chi. Cocchi made the fountain at the park his turf. The Yamada's first saw him at the end of the 7th book. In volume 9, he waits for Chi to come and pounces on a kitten that looks similar to Chi when he was searching for her. After Chi shakes off the leash and finds him, they go to a woman's home for food. Chi then falls asleep on a road and they almost got run over. Cocchi falls asleep too and they are taken to the Yamada's home. He goes back to the park because he couldn't get used to Chi's home. In volume 10, Cocchi and Chi plays with two kittens that look very similar to Chi and might be her siblings. Afterwards, a woman gives him food in an alley and calls him Tiny.
