Gren said nothing as Kuhaku went to scout ahead. He wondered what he wanted to talk to him about, but Gren figured that it must not be that important, at least not right now. He didn't really like the idea of Kuhaku going ahead of him, least of all alone. While the tiger faunas was no doubt much better suited for stealth operations than Gren was, he worried about what would happen if Kuhaku ran into the enemy and couldn't escape. The irony did not elude him when it turned out to be the other way around.

Gren was lightly jogging after Kuhaku, trying but ultimately failing to be as quiet as he can. While his armor was actually padded to ensure that it did not clatter, his footsteps echoed throughout the hall. But they were practically silent when suddenly there was a screech, like from a steam pipe, followed by heavy metallic footsteps. [b]"Dammit..."[/b] Gren took out The God Eater and prepared himself for the ensuing battle. Soon he faced the new opponent; a giant mech who was much too large to have any business in these tunnels, or so Gren thought. Perhaps the school put this one here purposely to test the student's skill against non-grimm.

Regardless, Gren did his best to fight back. When the mech activated it's machine guns, Gren countered with his own. He could not sustain the fire for long however; while he had the luck to fire first, his firepower matched the mech's, but the mech had much better armor. While Gren did some visible but minor damage onto the machine, Gren had to flee when the robot was able to return fire. The orc only suffered a few grazing bullets which bounced off his armor, but he knew that if he tried to stand toe-to-toe with the mech, the much larger machine would win in a battle of attrition. Gren could survive it's attacks but not for long. He'd need Kuhaku's help distracting it so that Gren could ready himself to attempt to take out the robot in one or two attacks. But he had a feeling that it would not be so simple as that.

Using the recoil from The God Eater, Gren rode his weapon like an uncontrollable and lethal jet bike through the caverns. When he saw Kuhaku he dismounted and stopped firing so his partner could hear him. [b]"We got trouble! A big mech, it's got heavy machine guns and who knows what else. I took some shots at it but I don't think I did much more than scratch it's paintjob. I believe it's protecting the artifacts given how tough it is."[/b] Hearing the machine approach Gren took to whatever cover could conceal him and readied for the next bout.
