Eto Shin

Eto Shin (エト・シン) is a living artifact that was created to act as a sanctuary for the survivors of the Sacred Kingdom Klystron after it had been destroyed long ago.

Appearance
Eto Shin is comprised of countless grains of sand that have been imbued with spatial magic in order to accommodate the thousands of people it has sworn to protect. It can alter its environment to suit whatever it feels will suit its host's needs the most. Inside its extra-dimensional space resides the core of its being.

Personality
Eto Shin is extremely loyal and dutiful in ensuring that it can protect the survivors of Sacred Kingdom Klystron. Over time, after all of the survivors had died off, that dutifulness turned into extreme loneliness and would use any excuse to entrap those that it encountered in order to protect them.
