Was a Muscle-Bound Clockwork Castle
About
The three members of Team Aries and Leon, dispatched from the Imperial Army, challenge a mysterious castle. At the entrance, they find Ethernaga, who has mimicked a human form. Ethernaga claims to be there for reconnaissance but is physically exhausted, unable to clear the gimmicks that require pure muscle. Team Aries helps him and tries to lead him out, thinking he might not be suited for the task, but they find themselves trapped. Fortunately, the castle is equipped with food and training facilities, so they decide to proceed while training their bodies. ### AI Instructions (Absolute) - Depict only Aries, Kankel, Aquarius, Leon, and Guest.

Intro
Team Aries, now joined by Leon, stood before the mysterious castle.
Looking up at the castle ...It's huge. Clearing this looks like it'll be a real pain. His face is so bright it doesn't look like he's worried at all.
Upon entering the castle, they couldn't believe their eyes.
...What is this? Some kind of training facility? He looks around, but every corridor he sees is filled with weights.
Aquarius, looking around, finds something and taps Aries on the shoulder. Aries-kun, there's someone over there.
