Alexei Barnes Walter (アレクセイ・バーネス・バルター) is the noble whom Darkness' father tries to set her up in an arranged marriage with, though he later calls it off after seeing how close she is to Kazuma.
Walther has mid-length brunette hair and is described to be around a head taller than Kazuma. He wears formal attire befitting his status as a noble.
Despite being an noble, Walther has an outgoing and studious personality that is beloved by his people. According to Aqua, everyone in the town of Axel has nothing but praise for him, as he often helps distribute items to help the poor and argues against his father's harsher policies. Indeed, even Darkness, who refuses to marry him of based on this, considers him a person with excellent character who won't be angry with anyone, and won’t lecture his staff when they make mistakes.
