Kaztano

 Kazutano''' (カズターノ) is a character who is important to Kyohei's group, especially Saburo, as he was the one who got Saburo front row tickets to see his favorite idol, Ruri Hijiribe, which were quite hard to obtain. It is believed that Kazutano is an illegal immigrant of unknown origin, though with an Italian flag and accent, the dubbers believe he is from Italy. (At one point Kazutano says "un poco," which means "a little" in Italian, but also in Spanish.) His name might be a katakana version of the European surname "Castano."

Characteristics
Physically speaking, Kazutano doesn't possess any unique traits and even seems to be a little overweight. He is a balding man, presumably in his late 30s to early 40s, and is usually seen wearing a red shirt and a small necklace.

Personality-wise, Kazutano is a bit eccentric but also very friendly and willing to help others, as shown when he aided Anri in escaping from the Yellow Scarves despite not knowing her personally. He is also shown to be fairly crafty when the situation demands it, such as when he manipulated his kidnappers into leaving clues about where they were going.

Dollars/ Mika Harima Arc
Kazutano is listening to music when a group of kidnappers enters his apartment. He makes a futile attempt to convince them that he is actually Japanese and then gets stuck trying to jump out of a window, making him easy prey for the kidnappers. As Kazutano flails around inside their van, one of the kidnappers, Kanazawa, tries drugging Kazutano with chloroform so he will shut up, but Kazutano kicks the bottle and it spills all over Kanazawa. Seeing that the kidnappers are affected by the chloroform, Kazutano manages to convince them to leave Kanazawa behind because the chemicals soaked into his clothing are making them dazed. The kidnappers agree with Kazutano's suggestion and leave Kanazawa in the trash with Kazutano's cell phone is his pocket. This act allows Kyohei and his gang to locate Kanazawa and rescue Kazutano, along with a little help from Celty. He is later shown drinking milk with Kyohei and Saburo while Walker and Erika interrogate one of the kidnappers. Later, he and Hashim appear during the Dollars meeting.

Yellow Scarves Arc
Kazutano and Hashim appear briefly to help Anri escape her pursuers from the Yellow Scarves. They let Anri go through a gate that Kazutano was hired to guard and lock it behind her, which slows down Horada and his thugs.

Dollars and Blue Squares Arc
Kazutano, along with several other members of the Dollars, appear to rescue the girls kidnapped by Asanuma and the other bad members of the Dollars.

Trivia

 * In the light novels, Kazutano was saved by Celty in the beginning of the story, while she saved Rio Kamichika in the anime. He was then set free while the kidnappers were dealt with by Kyohei and his group.
