I started reading manga since I was 10 and although I don't read that much now, I'd say a fair bit. Definitely 100 or so at least
100+, most of them are shoujo oneshots. And I started in late 2019. But now I have stopped, due to LNs and... er, Blackjack.
200-500 I started in 2018 or 2019 but I don’t read as much as I use to NUF dragged all my attention away and some other things did too
Are you asking series or book count? Page count? I choose 100 because of how many series, but going by anything else. You need larger numbers. Like in the thousands. Lol
I bring you my MU profile. So, uh, thousands if you look at how many series are on all my lists. But if we're just limiting it to manga I've finished (not including oneshots), then... 3146. EDIT: For the record, I've been reading manga since I was in... late elementary school/early middle school? So back in 2005 or 2006 thereabouts. A few years before the Borders collapse and the manga bubble burst. Been a while.
What other long reading peeps said. Somewhere in (low?) thousands. Its been a while since I last read a new one, but from 2011 to 2018-2019.
200+ I probably read more but since I actually never recorded them on MU or something like that I can’t say. Started in 2013 with dragonball
Jeez, you guys have read so many I think I have read/am reading 30-40 different series? Though I mostly read physical volumes so I guess that's a part of the reason why the number is so low. I started reading manga in like 2018 ish? I think??
