sekiha tenkyoken
The ultimate technique of the School of the Undefeated of the East, used by Master Asia and Domon Kasshu (which he learned from the former some time after obtaining the God Gundam). This technique focuses power into both hands of the user and released as a massive ball of energy that obliterates everything in its path.
It has many variations, which includes the Sekiha Love-Love Tenkyoken.
