Executed by pressing Heavy Punch and Heavy Kick simultaneously, E. Honda pumps himself up as his body momentarily turns red. Steam arises from his head region as a symbol of his increase in intensity of his Sumo Headbutt. By pressing Heavy Punch and Heavy Kick during while this V-Trigger is active, E. Honda performs the Oni-Daikaku, a more potent version of the Sumo Headbutt that can power through his opponent's attacks.
By pressing Heavy Punch and Heavy Kick upon hitting his opponent with the initial headbutt, E. Honda performs the Oni-Muso, which is an additional Sumo Headbutt.
Unlike to his second V-Trigger, Onigawara is 3-bars, meaning that E. Honda has to sacrifice a decent amount of health in order to obtain it. However, Onigawara can be cancelled from E. Honda's normals or special moves, such as Hundred Hand Slap. This gives him an easier way to confirm into his first V-Trigger and converting his combos.
While this V-Trigger is active, E. Honda can perform the enhanced version of his Sumo Headbutt by pressing Heavy Punch and Heavy Kick simultaneously. It can combo from any normal attack, unique attack, and his Hundred Hand Slap. It also causes a knockdown on hit. However, performing the Oni-Daikaku consumes slightly less than half of his V-Gauge. In addition, the initial headbutt is -4 on block. Because it leaves E. Honda close to his opponent after the move, they can punish him with one of their 4-frame Light normals for a small combo.
Oni-Daikaku also has one hit of armor on start-up. During a fully charged version, it and can cancel into a second headbutt, the armor lasts from the startup until the attack's active frames. Additionally, he is invincible to projectiles. This allows E. Honda can use this special move to power through his opponent's moves, including Critical Arts. On top of that, a fully charged Oni-Daikaku causes a guard break, giving E. Honda a free opportunity. However, the damage scaling after the guard break is very significant. While E. Honda can get a free hit or combo after the guard break, the amount of damage he can inflict is minimal due to the scaling.
Oni-Muso, which is the second headbutt performed after the initial headbutt, can only be used if Oni-Daikaku hits the opponent. It also drains almost half of E. Honda's V-Meter. Oni-Muso can be cancelled into his Critical Art for optimal damage.
