Also known as: 日ノ本零子
The protagonist of Rumble Roses. Voiced by Hidaka Noriko. Her Heel version is Rowdy Reiko.
Reiko enters the Rumble Roses tournament after her mother and sister disappear.
Reiko has short Brown Hair, Brown Eyes, and Medium Breasts, the left one having a mole. Her wrestling outfit consists of a Red Choker (sometimes a scarf in illustrations), a Red Bikini top, red Fingerless Gloves, red Short Shorts, and red Knee Boots that are cross-laced. Her shorts are unzipped, revealing her White Panties.
The first kanji on Reiko's name, "零", means "zero", which is alluded in her outfit, as both her panties and bikini top have the word "Zero" on them.
When fighting in a Swimsuit, she wears a front and side-tie polka-dotted White Bikini and white High Heel Sandals.
