Mikazuki

is a stray kitten that became the wandering pet of Mitsuki.

Personality
Mikazuki is a very affectionate and active kitten. But at the same time, he is rather arrogant and smug, which Mitsuki himself noted. Mikazuki does not hesitate to climb into the owner's bed, even if he is against it, and demands to play with him at any time. He is also freedom-loving and can leave whenever he wants, but at the same time return unexpectedly. Mikazuki has a sense of bad people, which was seen when he defaced wooden pieces in the yard of Daizen Matsushige's shop, and then lunged at him and scratched his chest, ripping off his scar's disguise, which allowed his crimes to be revealed.

Appearance
Mikazuki is a black and white kitten with blue-greenish eyes. It has a yellow collar around its neck. He later receives a red collar with a bell from Samidare Amaashi.

New Era
He first appears when he watches Mitsuki pass by with his mother. Later, he ends up in the same alleyway where Nezumi Kaitō was hiding from the police, and the thief fed him the stolen jewelry. After everyone in the alleyway is arrested, Team 7 finds the kitten, and since Sarada and Boruto couldn't take it in, Mitsuki briefly brings it home. Along the way, he runs into a man who explains how to properly carry the kitten, as Mitsuki carried it by the scruff of the neck the whole way. At home, the kitten is getting used to it and, when Mitsuki goes to bed, climbs into his bed. After several unsuccessful attempts to send the kitten to sleep on the floor, Mitsuki resigned himself and left him with him. The next day, Sarada and Boruto advise Mitsuki to give the kitten a name and also not to feed it human food, as he wanted to buy him a burger. Mitsuki buys milk, food, toys, a carrier and a collar from the store. At home, he puts a collar on the kitten, pours milk and gives the name - Mikazuki.

Released from prison, Nezumi, who wants to take the jewels, tracks down Mikazuki and, when the kitten becomes ill and Mitsuki takes him to the hospital, steals the carrier along with Mikazuki inside. He enters the gateway and tries to open the kitten's stomach, but Team 7 and a police squad led by Kōtarō Fūma arrive at the crime scene, prevent him from doing this and arrest Nezumi. Mitsuki takes Mikazuki to the vet, who turned out to be a man who told him how to properly carry the kittens, and he successfully performs the operation, returning Mikazuki to his owner. After the kitten has recovered, Mitsuki goes out with him for a walk, but Mikazuki's mom comes over and he leaves with her. Despite this, the kitten returns to Mitsuki that evening and he allows him to leave and come as he pleases.

Some time later, when Mitsuki was walking in the rain, Mikazuki comes out to meet him and escorts him to the alley where the wounded man was. Mitsuki takes him home and provides first aid. When the wounded man woke up and gave his name, Mitsuki asks for salvation not to thank him, but Mikazuki. Samidare agrees, and later gives the kitten a gift - a collar with a bell. He tells Mitsuki about a sister with the same name as the kitten before leaving. The next day, Mitsuki is walking with Mikazuki and they meet Samidare again on the bridge, from where he leaves after a little conversation. In the evening, when it becomes clear that the city's notorious criminal who killed the three people was Samidare, Mitsuki arrives at the cemetery and stops his deeds. Mikazuki approaches Samidare, who is lying in the rain, and begins to lick his hands, and after the wounded man is taken to the hospital, where Mitsuki leaves him a collar with a bell that Mikazuki gave him.
