Same as Kai-mon Kai except as noted above and as follow. The user opens the fourth
gate. For the duration of the technique, he gains a +30 to Strength, Dexterity, and Speed scores. His effective Chakra Signature when sensing Chakra increases by +2, and he gains a +120 enhancement bonus to Chakra Pool. He also gains a +4 bonus to Initiative checks.

Every consecutive use of any Gate-release Hachimon Tonkou technique within a 24 hours period reduces the bonus Chakra granted by opening a Gate by 40.

The user can only perform this technique while under the effects of Sei-mon Kai or with
sufficient degree of mastery in it.
