Eka activated Aqua Hide, so the five Holders couldn't see him. They only noticed his presence, not his physical form. He appeared in front of the 2-meter-tall armored monster and slashed with his sword.
The sword cut diagonally, piercing through the monster all the way to its chest. The humanoid monster held the sword and snapped it before charging back and also slashing with its own sword.
Even though the armored monster was almost cut in half, it could still move pretty fast. There was nothing but metal inside its body.
Eka dodged to the side and punched without holding back.
With a strong impact, the monster flew to the side, hitting the wall and making a crater!
