If you can, try autoclick on a private server, since you have kaneki’s kagune , because of its speed you wouldn’t risk dying to a high aogiri member. If you don’t have a vip server, hard grind ‘Reputation’ as it’s basically more yen as you get yen manually. Since yen is collected by just killing, you don’t need to pick up the body. If you’re a low level I suggest going for levels before kagune, because higher the level, the easier it is to farm yen.
A way to farm yen not in a vip server is by going into any server (preferably empty) (use ROBLOX+ (Google extension)) to scroll through servers faster. Go behind mister’s warehouse (there is a spawn spot there and auto click but stay near your device in case you are killed.
If this is not working (maybe because of rking) ask a friend or rando for permission to use their private server.
Autoclicking overnight is a very good way to farm yen.
