* Surname First name {nickname} (age)
| Shozu Kaya: |
An acquaintance of Ryuji and his late father. Seems to have forgiven Kuryugumi for causing her grief. (See long story no. 2 and long story no. 3) Currently living with the Kozukis and acts as their older sister. Particularily loves Tsukasa because she reminds Kaya of her late sister. Warmhearted, beautiful and easily moved to tears. Is scared that someday Tsuaksa will disappear like her sister did. One of the few people who knows that Tsukasa's a girl. Would very much like to see Ryuji and Tsukasa get together. |
| Kiryu Shigenori {Shige-chan}: |
The principal of Rokuominami, Tsukasa's junior high school. A nice, fatherly man who cares about his students. Defended Ryuji on several occasions, and is greatly admired by his students. |
| Iruma Masashi {Masa, Maa-kun} (7): |
Son of the landlord where the Kozukis and Kaya move to after they leave Ryuji's Western style home. Since his father's business is not doing well, he's not well off and he's clothed in stuff for 12-year-olds. He's a bit cheeky and acts older than his age. Wants the strength to protect both his father and the building in which he lives. Hates the rich and the yakuza until a certain incident occurs. He's in grade 2 and he's Isahaya's only friend. |
| Iruma ? (41): |
Masashi's father. Realized his dream of owning an apartment, something which he and 2 friends had wanted for a long time. Borrowed money from Tenko and now is in debt. Left only with his son as his wife ran out after being harassed by yakuza hired by Tenko. Finally has occupants in his appartment - the Kozukis and Kaya. |
| Tenko Isahaya (7): |
Grandson of Tenko who is to inherit a huge fortune. Masa's friend. A sweet, pure child. Lost his parents in an accident and has lived with his grandfather since. Carries a teddy bear with him and calls it Maa-kun (after Masa). |
| Tenko: | Old man who loans out money to people. Isahaya's grandfather. Filthy rich. Lives in a castle for a house. Hired yakuza to torment Iruma when he felt like he was losing Isahaya's love. Has a stubborn personality but loves his grandson dearly. Changed for the better. |
| Izushi ? and Yabu ?: |
Two of Tsukasa's former classmates. They're always together and sometimes it's hard to know which is which. I think Yabu is the one with the dark hair and Izushi is the one with the light coloured hair. Risked their school career to keep Tsukasa from being expelled. Do not know that Tsukasa's really female. |
| Onda ?: |
Friend of Takuma from high school. Lost his parents recently and left him with a debt of 80 000 000 yen. He kidnapped Takuma, Toshi and Sho in hopes of paying it off. (See episode no. 23) Changed after meeting up with Takuma again. |
| Shimada ?: | One of Tsukasa's classmates. The one without the glasses. Has light coloured hair. Fears Ryuji, although has become friends with Tsukasa. |
| Kudo Tsukasa: | One of Tsukasa's classmates. The one with the glasses. Has dark coloured hair. Greatly fears Ryuji although has become friends with Tsukasa. Has a sudden personality change. Looks like he had secret feelings for Tsukasa, as seen in episode no. 68. |
