Oni

ghost, devil

Mnemonic

A comet slams into a field, scorching the earth. From the smoldering crater, two monstrous legs rise, kicking aside a tent that campers had pitched nearby. An oni erupts from below, born of cosmic fire—its legs leave burning prints across the ruined field as it roars into the night.
Additional thoughts
Picture the comet as the oni's horn streaking down, the field as its domain, the tent torn like paper by its fury, and those legs stomping upward from hell itself.
Quick recall
A comet hits a field, legs burst from the crater, shredding a tent as an oni emerges.
