Iwashigahama Japan Women's Pro-Wrestling

Iwashigahama Japan Women's Pro-Wrestling (鰯ヶ浜日本女子プロレス), IJWPW for short, is a women only profissional wrestling organization headquartered in Iwashigahama.

Harmageddon Yoko
Harmageddon Yoko (ハルマゲドン陽子), also known as the "Demon Coach Yoko" (鬼コーチ陽子), is the main representant of IJWPW, a heavyset woman often seen carrying a shinai (bamboo training sword) who used to be a famous wrestler herself. She was forced to retire years ago due to hurting her neck and waist in a match against Black Widow. In the Street Fighter Alpha series she appears in some of R. Mika's victory animations. Harmageddon also writes Mika a letter encouraging her to press on towards her wrestling career with confidence, enduring the hardships that continue to come her way just as Yoko did. Yoko reveals that she had a wrestling colleague who talked with the same brusque mannerisms as Mika. Her nickname is simply "Frisky".

Yoko's first name in kanji means roughly "bright child" and is cosmetically identical to the kanji combo for "proton", read as "yoshi" instead of "youko".

Sunrise Nishisenba
Sunrise Nishisenba (サンライズ西船場) is an ace wrestler from IJWPW that Harmageddon had invited to join. She was notoriously clumsy in her debut. As her chokehold is weak, she prefers to use brute force and throwing techniques. Her special move is the Lariat Tequila Sunset.

Maple Storm
Maple Storm (メイプル・ストーム) is a IJWPW rookie. Despite being new to wrestling, she is a former athlete that was part of a women's football team in Canada and participated in the professional league, but the team was disbanded after a scandal with the coach. After watching a Japanese DVD with Harmageddon Yoko, she was impressed with her and decided to join the IJWPW. She is still studying Japanese and became good friends with Nadeshiko. Her special move is a strong tackle named Klondike Gold Rush.

Raika
Raika (雷華) is IJWPW's tag team champion. She has high stamina and jumping ability.
