Summary
Kinuhata Saiai is a Level 4 esper and an operative of ITEM, one of the organizations belonging to Academy City's Dark Side. Despite being a powerful esper and taking her assignments seriously, Saiai isn't as screwed up as her teammates Mugino and Frenda, and when she's outside work she's a perfectly sociable person who enjoys watching C and B movies and tease other people, with her usual target being Hamazura Shiage.
Saiai was part of the Dark May Project, an experiment that, in an effort to replicate the #1 esper's powers, forcibly altered young espers' minds by inserting Accelerator's thought patterns to try to steer their powers towards his vector manipulation abilities. While the experiment didn't achieve its goal, it did manage to alter the participant's powers and personalities. Saiai is considered the "honor student" of the project, as her esper power became an automatic defense that also increased her offensive capabilities like Accelerator's and her personality was still stable, unlike Kuroyoru Umidori.

Notable Attacks/Techniques
- Offense Armor (窒素装甲 (オフェンスアーマー) Chisso Sōkō (Ofensu Āmā), lit. "Nitrogen Armor"): Saiai's Level 4 esper ability. Speculated to have initially been some sort of atmospheric control-type ability by Kakine Teitoku, the Dark May Project turned it into an ability that allows her to control the nitrogen of the surrounding air to automatically create a thin barrier around herself. The thin super-compressed barrier of nitrogen has the primary function of working as a 360 degrees defensive barrier, easily stopping bullets and other powerful attacks. Additionally, Saiai can control the compressed nitrogen to mimic superhuman strength, allowing her to easily lift heavy objects like cars with one hand and to destroy walls with a single punch. However, her effective range is very small as it only extends a few centimeters from her palm. She is also somewhat capable of manipulating air currents around her via displacing nitrogen. Despite her armor, sufficiently powerful blows can still knock her down due to her small body, even if she doesn't receive any damage from the blow. In order to compensate for foes who prove to be able to eliminate naturally-occurring nitrogen in the air, Saiai carries around a small canister of liquid nitrogen for use at all times.
- Marksmanship: While not part of her usual fighting style, Saiai is skilled using handguns, having used one and a special bullet to take down a Six Wings from a moving car. She's also capable of aiming her handheld missile launchers accurately at targets hundreds of meters away.
- Handheld Anti-tank Missile Launchers: Saiai carries several of these devices. The handheld missile launchers look like a metal rod about 30 centimeters long with masses of metal about the size of drink can at its end. Appearing like maracas or old stick grenades, the handheld anti-tank missile warhead sare used by pulling the short string at the back ends of the rod, similar to have one uses a party cracker. When launched, they travel for about 10 meters and then ignite, capable of traveling 500 meters while scattering flames. Upon hitting something, it then explodes. A few of these used together are enough to nearly collapse an entire building.
