Atomic Samurai's Disciples vs. Evil Natural Water

Atomic Samurai's Disciples vs. Evil Natural Water is the fight between the A-Class heroes Iaian, Okamaitachi, Bushidrill, and the executive of the Monster Association, Evil Natural Water.

Prelude
Atomic Samurai's Disciples chase down a monster that managed to escape their initial attacks, who arrives at a room which contains Evil Natural Water and Mad Doctor Fish in a glass tank. The monster breaks the tank, releasing the Mysterious Beings to defeat the heroes, but is attacked and absorbed by the creatures while the three Disciples watch in horror.

Battle
Evil Natural Water launches several of the Mad Doctor Fish at Iaian, who deals with them rather easily. However, after just a single jet of water pierces Iaian's sword, the hero quickly realizes the hopelessness of the situation, mulling over about how their master has yet to teach them the method for "cutting water". Despite the forlorn situation, the three Disciples take their stances and prepare to do whatever they can.

Trivia

 * There are a few art inconsistencies. After Iaian's sword gets pierced, it appears to be fixed on the very next page. Likewise, a few panels featuring the Disciples lack their injuries, scuff marks, and apparel damage they sustained while fighting Devil Long Hair.


 * In the webcomic, Evil Natural Water was never put in a tank; the monster merely came across the three heroes in the hallway. Additionally, the monster that unleashed Evil Natural Water and the Mad Doctor Fish are manga original.
