Chiaki Tanimura

is a member of Red Tail who can use four guns simultaneously.

Appearance
Chiaki is a slim, petite girl with short black hair and a small bust whose expression is often a deadpan. She wears the Ishiyama High School uniform and her skirt ends above the knee, but beneath it are remodeled airsoft guns strapped to her thighs but in the anime, they have become highly pressurized water guns.

Personality
She doesn't speak much, often using hand gestures and nods to express her meaning. Despite her standard expression and tendency to shoot first, ask questions later, she appears to have more of a feminine side than many of her fellow Red Tail members. She usually refers to girls who make cute faces [happy, innocent, etc.] as "so cute" especially to Aoi.

She also tends to shoot men that are hitting on Kunieda except for Oga as she realize that Kunieda is in love with Oga.

Chiaki is first introduced along with fellow Red Tail member Aoi and Nene following the girls' return to school. While walking the hallways, a boy dives to the floor in an attempt to see her panties and she shoots at him until Aoi recommends she stop. She and Nene go to confront Oga soon after about his previous encounter with Aoi, and when they end up badly injured in the infirmary, the incident is blamed on him. In fact, they were beaten up by the MK5 in order to force Oga and Aoi to have a serious fight. Later, she and Nene encounter Furuichi and Oga at a swimming pool, where Furuichi's former upperclassmen unsuccessfully flirt with them.

When the vast majority of the Ishiyama High student body challenges Oga to prevent him from reaching Tōjō, Chiaki is among the Red Tail group who intervenes.

Saint Ishiyama High Arc
After the school's demise at the hands of a overpowered Oga, Chiaki and the rest of the Red Tails had to go to school at St. Ishiyama High, in room 3F while their school was being rebuilt. She appears as a support character and takes the outfit of a cheerleader to support the Ishiyama gang during the Six Horsemen vs. the Ishiyama gang volleyball match.

Fighting style
She mostly fights with her twin air guns, though she has the ability to use four simultaneously. (As seen in one episode of anime where she defeated MK-5 in split second.)
