KanjiJLPT N1
Barbarian

Mnemonic

Icarus crashes into a jungle swarming with massive insects. These savage bugs are true barbarians — crude, brutal, and utterly wild. They drag icarus to their mud throne, smear insect goo across his face as war paint, and crown him their barbarian warlord.
Additional thoughts
Picture Icarus on top, falling onto a throne of insects below — matching the kanji's top-bottom structure. The jungle insect tribe worshipping a fallen sky-god locks the savage imagery in place.
Quick recall
Icarus falls into a horde of insect Barbarians who crown him their savage warlord.
