"Skill—Ultimate Kaioken."
"Skill Level—B. Upgradeable."
"Skill Multiplier—1–6 (the current host can withstand multiple gravity and activate 6x Kaioken, but this will put some strain on the body). Note: Kaioken increases power by a multiplier."
"Additional Attributes—Reduced Consumption (Active), Burst (Active), Suction (Active), Adaptation (Active)."
"Advanced Kaioken Hidden Attribute—Kaioken Shadow Strike (Active)."
"Kaioken Shadow Strike—A phantom appears behind the body. When using Kaioken, whenever power builds to a certain peak, the phantom will appear and unleash a deadly strike.

"Advanced Kaioken Other Skills—Kaioken Shockwave (Active), Unbreakable Body (Active), Kaioken Flame (Active)."
"Ultimate Kaioken Hidden Attribute Enhancement—Unknown for now."
"Other Attribute Enhancements—Improves physical fitness, increases the Invincible Body Effect, and raises the Stamina Limit."

He had used this skill almost every time under truly terrifying circumstances. Perhaps using it so
