haniwa (statue)
Terracotta clay sculptures buried with the dead as funerary objects during the proto-historic Kofun period in Japan. Various types of haniwa were created, ~ soldier, horse, dog and other animals.
The haniwa soldiers wear ancient-style body armors, tentatively called tankou (lit. short armor) or keikou (lamellar armor) by historians. They are not counted as Japanese armor.
Hanny, one of the monster tribes in the Alicesoft games are modeled on these haniwa figures.
They appear in Animal Crossing as gyroids.
In Blue Archive, haniwa exist as skill level up materials. Strangely, they're bright pink and resemble a sex toy.
