|Appears In||Atelier Iris: Eternal Mana|
Zwei is a character in Atelier Iris: Eternal Mana.
Zwei is the second knight of the Knights of Alkavana. His skill as a knight is the highest among the five, but he dislikes being a leader. Because of this, Ein is the current first in command of the Knights of Alkavana, but Zwei works beside Ein as if he was in charge.
Zwei looks like a calm, cool character, but he is quite hardboiled. Whenever Ein gets out of hand, Zwei is usually the one stopping him. Back in his old days, Zwei was helped by Beggur. He joined the knights to show his appreciation towards Beggur, but he tends to act on his own.
