Grandpa Arlert (Junior High Manga)

Grandpa Arlert is the grandfather of Armin Arlert and lives with him.

Appearance
Grandpa Arlert is an older man with thin hair and a slight hunch. He is usually seen wearing a light turtleneck.

Personality
Much like his grandson, Grandpa Arlert is a timid individual. Despite this, he tries to come off as tough and intimidating to visitors; this is especially after Armin told his grandfather he did not want any visitors.

Story
After Armin was embarrassed in a dodgeball competition, Mr. Arlert was told by his grandson not to let anyone see him. During the next school year, Mr. Arlert heard the doorbell ring and several of Armin's classmates were there looking for him. Arlert tried to intimidate them into going away but one of them, Mikasa, eagerly looked forward to the thought of beating him; this caused Mr. Arlert to back down and allowed them inside.
