It actually is pretty impressive of a gag manga to be this memorable to me. I didn't even realize it's been over two years since I last read this. Hell, I didn't even realize I wasn't fully caught up since I hadn't read 31-35 before this newest chapter. The characters and plot though are so memorable that even though two years have passed I was able to pick this back up without a reread and I could remember who everyone was and what was going on. There are manga that I could go 2 months without reading but had forgotten everything about. This silly isekai gag manga about a shark though? I remembered everything.
Very impressive.
