Boku no Pico

Pico

Pico (ぴこ, Piko) is a blond boy who works part-time at Tamotsu's grandfather's bar in the summer. He's often shown swimming, usually naked or in a blue Speedo. He has worn girls' clothing ever since Tamotsu gave some to him as a gift. Later, hurt that Tamotsu wouldn't define their relationship, he rebels by cutting off some locks of his hair and runs away. The following summer, he spots Chico swimming nude in a stream while cycling by. He soon becomes friends with Chico, who calls him "oniichan" and forms a sexual relationship with him. In his relationships with both Mokkun and Chico, he is the uke, though the latter is somewhat reversible.

Tamotsu

Tamotsu (タモツ) is also nicknamed "Mokkun" by Pico. He is a young man who sexualizes Pico. Tamotsu is a white collar worker and regular of BeBe. A 22-year-old man who seduces Pico mistaking him for a young girl, but continues the relationship after realizing Pico's true gender. He later buys Pico a girl's outfit, complete with a ruby choker and panties, which he persuades Pico to wear despite his initial protests. He views Pico solely as a sexual object, though later shows true concern for Pico after he disappears. Although he eventually reconciles his relationship with Pico, he is absent in the second and third OVA. In his relationship with Pico, he is the seme.

Ojiisan

Ojiisan (おじいさん) is Tamotsu's grandfather who runs a large but usually empty bar by the beach named Bebe. When Tamotsu visits him for the summer, he has Pico help out as waiter while wearing a frilly pink apron. He introduces Pico to his grandson Tamotsu and suggests they spend time together.

Chico

Chico (ちこ, Chiko) is a brunette boy who lives with his sister in a large house in a secluded forest area and develops a sexual relationship with Pico in the second episode. He is younger and less sexually experienced than Pico. He often plays outdoors nude and secretly watches his older sister masturbate. In most cases, Chico is the seme, despite his age, though his relationship with Pico is somewhat reversible.

Oneesan

Oneesan (お姉さん) is Chico's older sister and she takes care of him. Perhaps because of her caring for Chico, and her isolated home, she appears sexually frustrated and masturbates regularly. After being seen by the boys through a crack in the ceiling, she is the indirect cause of their experimentation. She has a large collection of fetish outfits and sex toys that Pico and Chico use without her permission. She later masturbates around a corner from the boys when she finds them sexually engaged upon returning from the grocery store.

CoCo

CoCo is a male with long, black hair who Pico and Chico meet in the third episode. It is subtly implied that Coco is actually of supernatural origin, a so-called "city fairy", due to some strange minor occurrences in his vicinity, though this is never explicitly confirmed. CoCo soon has sexual relations with both Pico and Chico. After inadvertently causing some friction in their relationship, CoCo decides to distance himself from Pico and Chico, though they do find him again at Tokyo Tower and three of them end up having a threesome . He is also the main uke of the three, but this can be reversed.
