Close Friends[]
Despite Mitsuhide's friendly demeanor, easy smile and the way he draws in others he has very few people he is genuinely close to.
Kiki Seiran[]
As Zen's aides, they are very close and are rarely seen without each other. They are great partners in combat, with their movements so in sync that it would be difficult to determine a winner if they dueled against each other. When he learned that Kiki's service to Zen came with a time limit, he became angry. He was upset not because of the fact that she was leaving but the fact that both Zen and Kiki had hid it from him for over five years. They eventually resolve their fight with a duel, with Mitsuhide requesting that Kiki see Zen's current goals through before she heads off to take over her duties as Seiran heir. Mitsuhide also accompanies Kiki to the Seiran estate when Kiki asks permission from her father to extend her service to Zen. While Mitsuhide deeply appreciates their relationship and treasures their time together, he has never considered dating or marrying Kiki or anyone else due to his extreme loyalty to Zen. He wishes to live his life by Zen's side, which would be difficult to keep as his top priority if he got married. However, he became unsettled and confused when Kiki confessed to him. This could indicate that he does have feelings for her, but refuses to acknowledge it due to wanting to protect Zen all his life. His later comments indicate that while he respects her and sees her as very dear to him his feeling for her are platonic.
Zen Wistaria[]
He is Zen's close aide, having been hand-picked by Izana to serve as Zen's attendant. While they initially had a rocky start to their relationship due to Zen avoiding him and keeping him at a distance, eventually they became best friends. Mitsuhide is one of the few people that Zen listens to when going through a stubborn streak. As such, Mitsuhide usually doesn't scold Zen unless absolutely necessary so as to not overuse his power. They are very comfortable around each other, and both find it easy to tease and fluster the other. Mitsuhide usually teases Zen about Shirayuki, while Zen often teases Mitsuhide about his denseness on various matters. Mitsuhide is extremely loyal to Zen, going so far as to not marry or date anyone because of his oath to protect Zen all his life.
Shirayuki[]
Mitsuhide is shown to care a lot about Shirayuki, telling her that not only Zen but also himself and Kiki have her back. He is like a big brother to her. When Shirayuki was about to set off to Lyrias, instead of giving her a handshake, he gave her a hug while telling her to not get sick.
Obi[]
Mitsuhide disliked Obi at first, not trusting him because Obi had almost killed Shirayuki, but now they have a good friendship. Mitsuhide and Obi still bickers from time to time, mostly because of Obi's teasing but Mitsuhide trusted him a lot, now that they are closer. He acknowledges Obi and is at ease to leave Zen or Shirayuki in Obi's care and protection.
Others[]
Hisame Lugis[]
Mitsuhide and Hisame's relationship with each other is like cats and dogs, particularly because Mitsuhide is Hisame's favorite person to tease. Their relationship started as a more antagonistic one due to Hisame's underhanded attempts to force Kiki to agree to an engagement with him as teenagers. Their relationship improved gradually over the years, to the point that Mitsuhide has even shared his room with Hisame when he needed a place to board for the night. They have also been seen drinking together (mostly due to Hisame cajoling Mitsuhide into it). Mitsuhide is still getting used to the fact that Hisame is engaged to Kiki.
Izana Wistaria[]
Mitsuhide respects Izana as the ruler. He was initially supposed to be working under Izana as his retainer. However, he was later on appointed by Izana to be Zen's aide instead.
