is a Japanese professional wrestler and actress, better known by the ring name Risa Sera (世羅 りさ Sera Risa). She is currently wrestling for Ice Ribbon and belongs to the theatrical company Mizuiro Kakumei as well as the show biz production company Miki Production. She is currently in her second reign as one half of the International Ribbon Tag Team Champions, while also being a former two-time ICE×∞ Champion. Sera was born in Sera, Hiroshima.After graduating high school, she moved to Tokyo and studied voice acting at Amusement Media Academy (AMG).In 2012, Sera took part in the audition for "Taiyo kara Plancha" (太陽からプランチャ),a movie collaborated with Ice Ribbon, and she won the main role on the condition that she had to actually make her debut as wrestler with other winners of the audition, which made Ice Ribbon's recruiting project likewise in "Muscle Venus." Until then, she used her real name Risa Okuda. against Isami Kodaka and Yuko Miyamoto in their last match,[12] then Sera challenged Narumiya to a hardcore tag match. They had the match on May 4 and Sera's team were defeated.[13] Sera demanded an even harder rematch with light tubes, but this was declined by management of Ice Ribbon, because it would be deviating from the main concept of the promotion. Sera declared that she would boycott the next Korakuen Hall event on June 24[15] but eventually she held her own event there after Ice Ribbon's event for just one match called "Human Hair Death Match" (人毛デスマッチ) and made peace with Narumiya after being defeated again.
Since then, Sera held two "Death Match" events collaborating with Ice Ribbon. They were made of fun matches by Ice Ribbon's wrestlers and really hardcore matches including ladders, barbed wires and light tubes by Sera, so practically she made the promotion compromise on the matter.
On November 14, 2015, Sera formed a new tag team with Maya Yukihi, and named the team "Azure Revolution".
On March 21, Sera challenged Hamuko Hoshi for the ICE Cross Infinity Championship, and defeated Hoshi by a diving double knee drop to win her first title as a single player. On May 3, Sera headlined Ice Ribbon's 10th anniversary event at Yokohama Cultural Gymnasium to successfully defend the championship against Yuka. Sera was defeated by Tsukasa Fujimoto at korakuen Hall event on July 3 and lost the title,but the title went vacant by the result of the November 3 event,and on December 31, Sera won the tournament for the championship, defeating Fujimoto in the finals, and regained the title.Sera held the title for a full year, losing it to Hiiragi Kurumi in her eighth defense on December 31, 2017
