oh, I'm a big one piece fan, also love One punch man, but I haven't been keeping up with the manga. Attack on Titan is also cool, but a bit too dark sometimes lol, and too many characters are killed off. Are you caught up with OP, the last chap was fire haha. Katakuri is badass, and I think we're at the end of WCI arc, probably will end at ch 900.
Yeah, I love OP all caught up too. It's amazing how a manga lasted this long and still be so damn good. I recommend you catch up with Berserk soon. Don't want to give out too many details, but I have a strong feeling we'll see Casca back to normal by 2020!
