Any good Comic Book/Anime/Pop Culture stores around Olso?

Hello Friends! I'll be in Oslo for a week in just about 14 days now and I was wondering if anyone knows of any "pop culture" to use an American term stores that had like Norwegian language comic books or Toys or Anime items? For someone familiar with the USA a basic Comic Book Store. Any leads would be appreciated. Would love to know if any place has any older back issues of comics as well! Takk!
