Birthday March 14th, 178cm, blood type AB. He is a doctor, but unlike Isshin who runs a small clinic, he is the director of the large Karakura General Hospital. He and Uryu don't meet often, so they aren't used to physical affection or seeing much of each other's lives. He is an Echt (pure-blood) Quincy and the last Echt Quincy existing in the human world. While he appears cold and ruthless on the outside, he actually loves his family deeply and is quite compassionate. There are speculations that Uryu's abilities stem from Ryuken, suggesting his potential ceiling is extremely high. Excluding Schrift abilities, his practical potential and intellect are top-tier.

He loves games and never misses a perfect score even while studying casually; he even dyed his hair yellow. Junya is the definition of a big-hearted person and truly loves and dotes on Naoki.

16 years old, 169cm. He is a class representative. At first, he seems like a well-off child with good grades who lacks nothing, but he actually suffers from discrimination and verbal abuse due to his mother's extreme obsession with education.

He really likes his older brother Junya and enjoys gaming. He has a weak spot for being called "Young Master" or "cute."
