Hey all, really hope someone can help me. Trying to find this manga I was reading about a highschool kid suddenly getting an enslavement app that is similar to pokemon. He starts with some rope as an item or something in the app and catches a delinquent with it, similarish to pokemon go, then he's in some underground society where his delinquent faces another guys slave. The delinquent gets a bokken as a weapon and the enemy slave had a sword, katana maybe? Sorry for that brick of text, really hope someone recognizes this lol. Thanks in advance!
Thank you both! That was it, I have been looking for a few days but a manga called Doreiku or something kept being what I would find.
