Achai isn't a trusting deer. He prefers to walk alone than run with a herd. He is somewhat territorial and will challenge any call made from another deer with his own call. Even as a foal, he acts as though he has the biggest set of antlers in the forest. Achai isn't sociable, either. If you walk up to him, he's most likely to turn his back on you and run off. He only hangs out with a special few deer. He is very over-protective of his sisters, Ageni and Achai. He doesn't like for them to be around other deer because he doesn't trust them. This goes against Ageni's nature, so she tries to avoid her brother.
