Abstaining from this poll. I am not sure what my first series was, and I am not sure if I should count the series which my older sibling read to me or the ones that I picked myself at a young age. It would be something like sailor moon, tenshi muyo, ranma 1/2 if sibling and it would be a no. Picked myself im not really sure.

Bleach. The Bount arc drove me to the manga, iirc, and I did keep up until it ended.

I'm a jack of all trades but master of none. Too many jars and not enough hands.

The first manga I read was also Doraemon, like 28 years ago and ofc I finished it including most of the adventure (haven't read 20+) mmm...

If it's online manga, I think the first one was Naruto, and I completed that one when the final chapter in WSJ came mmm...

I will change this world mmm...
So the world can change me mmm...

Oh my god that unlocked some memories for me. PET and Happy Happy Clover were the two manga I remember our library always getting the most recent volume of. I wonder if they're still available anywhere...

Ha, my first was ToG. It's forever on the list of maybe some day I'll go back and read. So yea lost interest and it's still ongoing.
