Kouji Tanaka

Kouji Tanaka is the second Ajin discovered in Japan. He is a partner to Satou. Tanaka shows a rather large resentment towards humanity after the daily torture and experiments he was subjected to during his capture. Other than this, he is rather impassive; not really getting frustrated or angry in many situations, and is completely unresponsive to bloodshed and gore. (Source: Ajin Wiki)
