Yuki Mahiro

Yuki Mahiro is a member of Anthos*. His image color is red.

Appearance
Mahiro has short red hair that's neatly combed and styled. He is among the shorter idols in the series, standing at only 174cm. He has large orange-ish brown eyes and a slim figure

Personality
A straightforward and solid person, he has a personality that is missing somewhere, and acts like a beloved younger brother to anyone who'll spoil him. He used to not care about his appearance, and his clothes were plain, so he is now wearing the clothes he received from other members.

"Even if you have something you don't like, you have the positivity to forget it as soon as you sleep or eat.

Anyway, I'm pure, I don't doubt people, I love the members of Anthos."

Kisaragi Kaoru
Kaoru is Mahiro's roommates, and he was also the first member of Anthos* that Mahiro met when they first moved to the dorms. The two share a very special relationship as they are of the same age. Kaoru once bought a stuffed rabbit for Mahiro, and they used that very same rabbit to film the initial official fancall of BIRTH.

Kagekawa Ryoga
Ryoga and Mahiro has a very close relationship, so close that Ryoga had called Mahiro his soulmate on his birthday, though Mahiro does like to tease him in some occasions. The two sometimes spend time watching movies together.

They do have occasional quarrels, as addressed by Mahiro in a 2021 September Q&A. However, there was one occasion in Project Archive 1-22 when their conflict erupted and Ryoga hit Mahiro in the face, due to him stating that he wanted to leave Anthos for good. They later reconciled in Project Archive 1-24, where Ryoga revealed to Mahiro that he was indeed friends with his older brother, Chihiro.

Kiyose Haruta
Since they are around the same age, Mahiro and Haruta (along with Kaoru) are very close, and they usually do silly things together to post on Twitter. Their combination name is called Rabion.

Background
Mahiro is the youngest son of President Amagiri Hajime. His older brother, Amagiri Chihiro, is none other than the Legend Class idol ChiHERO, who was once widely beloved but has disappeared from the idol world, claimed to have committed suicide.

It was implied that Amagiri sent him to a military school.
