List of Nana Characters - Main Characters - Black Stones

Black Stones — normally shortened to Blast (ブラスト, Burasuto?) — is a popular punk band within the series. Ren was once a member of the group, but, after his departure to join Trapnest, they recruit a new member, Shin. They attract a large following, and ultimately sign a deal with Gaia Records. Nana Osaki is their main vocalist.

Nobuo Terashima (寺島伸夫, Terashima Nobuo?) a.k.a. Nobu (ノブ?)

Voiced by: Tomokazu Seki (Japanese), Matthew Erickson (English)

He is the guitarist of Blast and was the only person able to befriend Nana Osaki during high school—which coincidentally began their shared love for punk music. He is friendly and optimistic, but at times, he tends to miss the focus of conversations around him. Before Nana's "smoking ban", he is the only non-smoking member of Blast. However, his threshold for alcohol is poor and he accidentally leaks many secrets while he is drunk (most notably, about Nana and Ren's relationship to Shin). Like Yasu, Nobu comes from a rich family (his parents own an inn). Despite this, he is still very passionate about music, even sharing Osaki's dream of making it big with a band one day. He falls in love with Hachi and they start a short but happy relationship. When Takumi tells Nobu about her pregnancy, Hachi painfully leaves him for Takumi. While he eventually accepts the reasons why she left him, he still fears the possibility of the child being his. He still has feelings for Hachi but decides to get in a relationship with Yuri. While he later claims he is "over" Hachi and appears happy in his relationship with Yuri, the aftermath of Ren's death allows him and Hachi to get closer. Following a heartfelt conversation in his dorm room, the two embrace and nearly share a kiss before Hachi pulls away, in fear that she will hurt both Nobu and Yuri. Nobu proclaims loudly that he "of course" still has feelings for Hachi, when scolded by Nana. He uses white Fender Stratocaster and black Gibson Les Paul Custom.

Shinichi Okazaki (岡崎真一, Okazaki Shin'ichi?) a.k.a. Shin (シン、シンちゃん?)

Voiced by: Akira Ishida (Japanese), David A. Kaye (English)

He is the bass player of Blast. He uses black Fender Precision Bass. Though mature and tall for his age, he is 15 years old and is the youngest member of the band. Although born and raised in Sweden, Shin's mother committed suicide while his mother's husband adopted him and refused to acknowledge him as his son. After moving to Japan, Shin met Ryōko Kawashigi, an airline stewardess, who works as his pimp and introduces him to alcohol and drugs. This leads Shin into moonlighting as a male prostitute with Reira being one of his "clients". Among other things, he is an expert mahjong player and a confidant and early roommate to Nobu. He sees Hachi as his surrogate mother when he voices out his wish to have been her child when she decides to keep her baby. He stops seeing Reira to protect her status and his own feelings—also possibly sparked from fear by Takumi's warning. After Shin retreats to Ryoko shortly after breaking up with Reira, the two were put under arrest for possession of marijuana which caused BLAST to withdraw from their tour. In the future it is shown he has become an actor.

Yasushi Takagi (高木泰士, Takagi Yasushi?) a.k.a. Yasu (ヤス,ヤッさん、ハゲ?)

Voiced by: Yoshihisa Kawahara (Japanese), Brian Drummond (English)

He plays percussion and is the leader of Blast, usually handling the business partnerships and financial decisions needed for the band's success. His favorite cigarette brand is "Black Stones", from which the band got their name. He is also a lawyer in training, despite his "scary" appearance (clean shaven head, many earrings and dark glasses). He is the big brother figure for Nana O—and sometimes Nobu—and acted as Nana's "guardian" when she arrived in Tokyo. While he admits to being in love with her, he baits Ren to rekindle their love for each other. Ren says that Yasu "always stood back and let have what ever he wanted" to Reira in chapter 53. Nana realizes that Yasu will always consider Ren's feelings first, and the reason Yasu will never pursue his feelings for Nana is not that he is "a prude" or loves her like a sister but because she is Ren's girlfriend. He looks after her in place of Ren, who can not. In the past, he shared several ties with Trapnest's members. Yasu and Ren grew up in the same orphanage and remained close friends when Yasu was adopted. He dated Reira while in high school and was jealous of Takumi's success and influence on her, which he later relates as the reasons for their break up. Also, he is the oldest member of Blast, which Nobu sometimes teases him about (by calling him "old man"). He is in a budding romance with Miu to the surprise of Ren and others—who were sure he would date Reira again. When Nana sees him with Miu having breakfast she immediately assumes they had sex and is obviously hurt by this thought, avoiding Yasu and even comically screaming that she does not care who he sleeps with after he asks her if she is alright (he was referring to the hangover she was complaining of when she entered his room).
