Kaoru Unagiya
Manga Debut: Volume 49, Chapter 426
Kaoru is the son of Ikumi Unagiya. He's best known for being a kid who gets caught up in his father's business dealings, though he's pretty much just trying to be a normal kid in the middle of everything. Fans often note that despite his young age, he shows genuine curiosity about the world around him—typical enough, but it makes him stand out a bit when you realize what kind of environment he's growing up in.
