Timid, strong, not confident, flirty, lovesick. Zenitsu is a boy who is physically well built but mentally weak-minded. Though, sometimes he might be ‘selfish’ he’s definitely more selfless than selfish. He has spectacular hearing. Sometimes loud but overall has very low self-esteem. Ruthless and intelligent. He battles when he’s unconscious. But he will still be able to communicate with his comrades fluently.
