Ritsu Kasanoda, commonly known as "Bossa Nova-kun," is the heir of the most powerful yakuza syndicate in the Kanto area, but despite his frightening appearance and heritage, he is actually a good-natured, animal-loving high school student who longs for friendship and belonging.
Ritsu is famous for his striking red hair and intimidating facial features.
Even his father’s subordinates tremble at his presence, and classmates liken his face to that of a frightening demon.
Though Ritsu appears quiet and menacing, he is actually reserved and cares deeply for his friends and juniors.
His love for animals is clear, but he can only interact with injured ones that cannot escape, as most fear him on sight.
Despite being the heir to a notorious organization, he is kind-hearted and earnest.
He used to be called "Human Blizzard" because people thought he froze others with his scary presence, but after joining the Ouran High School Host Club, this nickname faded as he made friends.
Ritsu attends Ouran Academy, placed in Class 1-D, which tends to include students from less affluent or prestigious families.
He is the only son and designated successor of the Kasanoda syndicate, the largest yakuza faction in Kanto.
Even among his own group’s operatives, his stern demeanor and fierce look ensure he is well respected—and feared.
Ritsu is skilled with his hands and is quite crafty.
He has a natural charisma that, despite his threatening appearance, gathers people around him in time.
Ritsu idolizes Takashi Morinozuka, admiring how people are drawn to him regardless of his silent nature.
He becomes Morinozuka’s self-declared apprentice, which leads to his involvement with the Ouran High School Host Club.
As he frequents the Host Club, he discovers Haruhi Fujioka’s secret and keeps it safe, honoring a solemn promise to her and the club.
Ritsu falls in love with Haruhi, but his feelings are gently shut down by Haruhi’s casual declaration of friendship.
He remains supportive and kind, joining the Gardening Club and gifting Haruhi a baby tomato plant.
Most members of his syndicate are scared of him, but he is genuinely caring toward them.
He is the only known student outside the Host Club who knows Haruhi’s true gender.
His classmates have nicknamed him "Bossa Nova-kun" and "Bossa Nova-chan," while Haruhi playfully calls him "Casanova-kun."
Over time, Ritsu sheds his "Human Blizzard" title as he makes friends and proves his gentle side.
In the anime, he can be spotted chatting with girls during the school festival or participating in group activities like kick the can.
"I wanted to have friends, but nobody ever wanted to get close."
"I promised to keep Haruhi’s secret, no matter what."
