Reika (零下) is a boss character from the Senran Kagura video game series. She makes her debut in Senran Kagura: New Wave during the NINJA†RIDERS event, alongside Mayumi and Hiroko, where they were described as bad students with a strange atmosphere.



Reika has a pale complexion and dark green eyes. Her raspberry hair is pulled up into messy pigtails.

Her normal outfit is a brown school sailor uniform, while her shinobi form appears to be a black form fit outfit accented with dark raspberry, pink, and white. White writing is on each breast, along with a strap that is held with a black ornament beneath her neck. She also wears matching gloves and shoes. On her head is a black headband with pale pink-white eyes and two tiny devil horns.


She seems to be a typical delinquent, though she is willing to do odd jobs for food or cash.

During the NINJA†RIDERS event, she and her friends appeared in their school uniforms as bosses, though they may have been under the influence of Reki who was the final boss of the event.

She and Hiroko (but not Mayumi) next appeared for the Yin Yang Shinobi Squadron 3 event, where they wore what would later be known as their shinobi outfits. However, this event was a Hero Show that Hisui was helping a friend with, and Reika and Hiroko were being paid to act as the villains, so at the time these costumes were just the villain suits for the production (hence why they say "Villain" on them), but later on these suits seemed to be treated as their actual shinobi forms.

Reika and Hiroko would later appear again to crash Mirai's Birthday Festival, wearing their villain suits and possibly under the influence of Reki again.

Her eyes are shown to be a different color during the times when she may be under the influence of Reki. The first time they were yellow, and the second time they were red.


Reika was a non-playable boss that appeared for events in Senran Kagura: New Wave.


  • Reika's name (零下) can mean "Sub-Zero".
  • Her Shinobi Transformation features the kanji for "Evil" and "Party" across her chest, and when taken together they mean "Villain."
