Atsushi is quite the curious siren, sometimes questioning when people uses deep words. Though, if people taught him, he would be a fast learner. He also takes care of white tigers infested in his island, whispering affectionate tones, understanding the tigers intentions despite not everyone knows what they're talking about. He's also quick at forgiving people no matter what harm they did to him. Plus, cannot leave the island, and very aware and timid.
