Lit. "Heavenly Phoenix Cross"
Souther's Nanto Ho-oh Ken ultimate technique. Souther takes a stance with his arms held out evenly, like a cross. As the name suggests, it is launched into a powerful aerial attack. This technique makes the user so light and graceful that he can glide over any physical attack.
Usually parodied with Rumia because she takes the exact same pose in Embodiment of Scarlet Devil, and Reiuji Utsuho because in Touhou Hisoutensoku she has a similar moveset to Souther in Hokuto no Ken Shinpan no Sousousei Kengou Retsuden.
