Notes:

(translated by /a/)

The kind who will endure all to determine victory (ok, I'm kind of confused what it's saying)

If there is Christmas…Gift! What kind of gift will he give?
Something along the line of a fountain pen or a plume pen, or a notebook. The kind of objects that are practical and necessary for daily life. It seems that he would give something that is very mature looking and stylish in the same time.

A Date! How will he plan for a date?
He will probably invite that person to his house. Only when it's an anniversary, he will abuse his rank, and prepares a luxurious meal for that person.

The important declarations! How will he invite you?
He'll probably directly say how thankful he is, and then say something direct yet classy kind of invitation: "let's live together!"

What are his charms?
He doesn't follow the flow, and doesn't change his beliefs. He will diligently follow and execute what he believes in; I think these things are hard to accomplish for ordinary people. Even though he's always under the situation in which his subordinates are constantly on the line, he does not bulge and always finishes what was tasked. This is rather awe-inspiring.

The absolutely necessary conditions to approach him!
Erwin is the kind of person who is ready to throw away his own name for the sake of humanity. For this kind of conscience, that person has to be on a similar level too. As a commander, he is very busy and probably doesn't come home very often. The key point is whether one would understand or not his dedication for works, and then support him.

Even under Nile's gunpoint, Erwin was not afraid and kept shouting instructions. From this we can see his conscience as the SL's commander.
