Alfonse is the first son of Walter Goldstein, making him the heir to the House of Goldstein. When they were younger, Alfonse and Klaus were very close. They had a huge amount of trust towards one another and supported each other, filing in where the other failed. Because of their close relationship, Klaus was the one who was hurt the most when Alfonse ran away. This caused a permanent tear in their relationship, to the point where Klaus cannot hold a conversation with Alfonse without getting angry. Alfonse didn't bother explaining why he left either, which angers Klaus even more. He also had a previous engagement with Elaine, who was his childhood friend. While they were close enough to be best friends with each other, their engagement was arranged by their parents. Three months before their wedding, Alfonse decided to head out on a brief journey to find a certain species of dragons to further his research. He was interested in their longevity and regenerative abilities, and because they migrate monthly, Alfonse had to chase a lead on their location urgently. Elaine proceeded to ask him if their wedding or his research was more important, to which he hesitated and answered that both were as important as each other. Upon hearing his answer, Elaine said that his research was more important to him, since he hesitated before answering and cancelled their engagement. She then told him that she was going to follow her own wishes like him. 

Alfonse is shown as a calm, easygoing, polite and caring person towards his friends, normally getting along with everyone except Klaus. Alfonse is somewhat carefree when it comes to certain obligations. Alfonse loves his family deeply, and is very obviously hurt and down whenever Klaus gets angry at him or keeps his distance. Alfonse blames himself for the pain he caused his brothers when he ran away. Because of this, he believes he is undeserving of love. Despite being calm and polite, Alfonse can be quite dangerous as an enemy. Alfonse is a genius like the rest of his family, and is very passionate with his field of research. This passion can sometimes be the downfall of his relationships due to how much Alfonse dedicates himself to his research. Alfonse is currently an official researcher for the Ministry of Magical Justice. At one point, Alfonse is also very naive towards the protagonist's feelings for him.

Voice: High to mid-high range, kind & caring, possibly a bit geeky/nerdy or brotherly.  We would love to voice match the former voice actor, but it is not needed. Example
