Sometimes it’s not the kid you expect who falls through to magicland, sometimes it’s … Elliot. He’s grumpy, nerdy, and appalled by both the dearth of technology and the levels of fitness involved in swinging swords around. He’s a little enchanted by the elves and mermaids. Despite his aversion to war, work, and most people (human or otherwise) he finds that two unlikely ideas, friendship and world peace, may actually be possible.
“In the distant future, exist a new life form called “Houseki” (gems). The 28 Gems must fight against the “Moon people” who want to attack them and turn them into decorations, thus each gem is assigned a role such as fighter or medic. Though they hopes to fight the Moon people, Phos (short for Phosphophyllite) is a Gem who is given no assignment until the Gems’ master Adamantine asks them to write a natural history book.“
