Kyuu

Kyuu-chan is Hinata's pet cat. Kyuu-chan is a white cat with light pink ears, front paws, small black eyes, pink socks, and a black bow tie.

Kyuu-chan is an extroverted, playful, and charismatic cat who can make friends with anyone and anything. He tends to take on human characteristics such as walking bipedal, wearing aprons, hats, and scarves. He's very attached to Hinata and likes to collect things and make them his friend.

Kyuu-chan is somewhat naive and childish in nature. Once when Hinata was crying from cutting onions, Kyuu-chan offered him some toys to cheer him up. He also tried to stick band-aids on Hinata’s face to “heal” him after Hinata expressed sadness about having spent a lot of money that month. He also did not have much monetary understanding, as Mari had to explain to him that 5 yen was not enough to buy a lamp. He will believe almost anything Hinata tells him, such as Santa delivering gifts, a “magic” towel, or an “arrow dodging school.”

Kyuu-chan is incredibly strong. He's able to do feats Hinata has trouble with, such as opening jars. He was also able to lift several 10kg bags at once at a construction site. He has trouble with sour things, namely lemons and oranges. When in presence, his mouth pluckers up.
