Another one of Kentaro's desperation moves: Koen Hyakkuretsu Dan (Tiger-Swallow Hundred Furious Bullet). A Fa Jin type of attack that charges ki into his fists as he unleashes a rapid barrage of punches, which discharges his ki upon impact. It usually finishes with one more powerful punch. The first part of the name comes from the fact that the attack is as fast as a swallow and as strong as a tiger.

It's mainly based on Kenshiro's "Hyakkuretsu Ken", Jotaro Kujo's "Ora Ora" attack and Pegasus Seiya's "Pegasus Ryuusei Ken", which are some of the strongest physical attacks I've seen in any manga. The only difference is that it doesn't use pressure point strikes or raw power.
