Amakusa is a rather quiet person and rarely talks. However, whenever talking about music he always mentions how "fate is written in the stars." He is extremely dedicated to HE★VENS, to the point of suffering emotional breakdowns. He is very hard to himself, as he believes he has to do anything to prove that he is a valuable member of the group. He was the last person to join HE★VENS and had issues with opening up to the other members. He eventually let down his guard and openly smiles and jokes around with everyone. He seems to be the closest to Nagi.
