Sen'enshu

Sen'enshu is a move Chun-Li has in the Street Fighter Alpha games

Description
Chun-li flips into a head stand while spinning her legs like helicopter blades, then slams her legs down in front of her, dealing a good amount a damage. The move could primarily be used as an anti-air, or as just straight up damage. Later in the series, this move turned into the Hazanshu, which is an improved version.
