Looking for an anime that was on netflix?

The anime was on Netflix and as far as I can remember it was even a movie.

The film is about a normal boy who is an employee of one of the biggest game companies (mobile game and pc in anime) and works in the security department (IT-talented) and later supposedly cracking the code of a big virus in this game world (He is a math genius and sits at the house of the "girlfriend" in the night to crack the code) (with a buddy in the room, looks like a college or something similar).

Suddenly a girl storms into the room and asks the two boys if they need a summer job. This holiday job is to go with her to her rich family and marry before them. Everything happened at the request of the grandmother who was very old and sick. I have also googled forever but just can't find the name and can't remember it 😅

I thank you already for your answers.

That's Summer Wars. The license is currently on Anime on Demand.

By the way, the protagonist is still a student. He just does a few maintenance on the Oz servers over the holidays as a summer job

Summer Wars

It's still available on Netflix.

Also a big thank you to you. It has been a long time since I saw this anime, so I confuse or confuse many things, but in the end, a few people know what I mean by that.

Habs just checked out, will be a long night today.

Well then have fun looking.

@ ibims1dummkopf thank you.

Yes, that happens to all of us. Over time, the memories blur something

But with a few key words we anime fans guess this very quickly ^ - ^
