Mitsuki Hyoudou/Relationships

Mitsuki has developed various relationships with different characters from the Supernatural World and the Human World. She is a well known and loved student at Kuoh Academy for her politeness and kindness. In the Supernatural World, Mitsuki is one of the most admired devils for low-class as she along with Issei represent that status in the Devil World.

Gorou and Miki Hyoudou
Mitsuki's parents. She loves them very much and they, in turn, love her. She is their most favored child as she exhibited more skill and intelligence than her brother Issei. It is this favoritism that causes Mitsuki to somewhat dislike her parents as she feels that her brother is being treated unfairly in the family.

Issei Hyoudou
"I'll always have your back, Aniki!"

- Mitsuki to Issei

"You’ve always had my back you know. Even when I couldn’t count on anyone, I could always count on you."

- Mitsuki to Issei



Perhaps Mitsuki’s closest relationship in the entire series. Their relationship is that of brother and sister, best friends, and rivals. Their relationship was originally antagonistic with Mitsuki lording over Issei the fact that their parents loved her more than they did him. However, this changed the day she got bullied and abandoned by her friends during middle school. Issei was the one who stood up for her and defended her. Ever since that day, she and Issei became extremely close. Irina comments that they were joined at the hip stating that where one goes, the other is not far behind.

"Well, you have to me because I'm older. ONLY BY THREE MINUTES, ANIKI! THREE MINUTES!"

- Mitsuki and Issei's most common argument

Out of all the members of Eden Squad other than Irina, Mitsuki is the one who knows Issei the best. While they bicker and fight due to their nature as each other’s self-proclaimed rival, Mitsuki does care about Issei very much. She tries to get him to express more emotion. Mitsuki frequently encourages Issei to take better care of himself much to the latter’s annoyance.

As twins, Mitsuki and Issei support each other to do better. They also get into meaningless competitions over who is better. Kiba often comments that the two have twin telepathy despite both Issei and Mitsuki refuting that fact. However, they can feel the pain of the other which allows them to go assist whenver they sense it. Their twinship contributes to their teamwork which is described to be extremely fluid. Azrael states that Mitsuki and Issei act as if they have fought side by side for hundreds of thousands of years.

Lily Hofferson-Hyoudou


Mitsuki's adoptive younger sister. Mitsuki acts as the big sister to Lily and Lily looks up to her in nearly the same manner as she does to Issei. Out of all the female members of Eden Squad, Lily is closest to her.
