Tatsuya Suou

Listen, you haven't seen Eikichi? I can't find him anywhere.

His relationship with his family is strained; he’s envious of and hostile towards his successful older brother, Katsuya, despite Katsuya’s best efforts to care for him, ashamed of his disgraced ex-police officer father whom he considers a coward, and disappointed in his mother for remaining passive when his father was discharged from his capacity as a police officer on false accusations.

The one consistent exception to his usual behavior is Jun Kurosu, with whom he shares an exceptionally close bond even within the Masked Circle itself irrespective of whether he is selected as Tatsuya’s love interest. The two are repeatedly likened to one another as children and teenagers, by themselves and other characters, each carries a memento of the other, and their exclusive Personas correspond to each other. Tatsuya’s emotional reliance on Jun is so great that when Jun’s feelings of despair upon being confronted with a duplicate of his mother created by Nyarlathotep nearly cause him to fade from existence, Maya is able to bring him back solely by reminding him of how alone Tatsuya would be without him.

Originally, Tatsuya was a caring, proud, self-confident person and it's in his nature to not leave people in need. He has a vague feeling in his heart to be a person who can express ideals to others like Maya did when they were young. However, he does not know exactly what to do with his life and spends most of his free time on his bike and mechanic work, seeking economic independence from his family due to his father's disgrace.

In Eternal Punishment, Tatsuya is characterized as a fairly passive individual and a brooding figure. Upon Tatsuya's first meeting with Maya, who has no memories of the original timeline, she refers to Tatsuya as the "déjà vu boy," swearing that she had seen Tatsuya somewhere. The Tatsuya of "This Side" has a pattern of skipping classes with a friend, Anna Yoshizaka.
