That is, a lot! Like a lot a lot! By my count that’s 134 volumes of unread physical manga, much of which is still of significant reading difficulty 
Finishing my unread novel/lns is just unrealistic rn, so not even gonna worry about those yet
I have no illusions about ever actually finishing everything I own, but it’d be nice to at least finish a few of the things I know I am going to want to read and then be rid of, or some of the easier series that I enjoy but have kinda gotten put on the backburner.
In particular, I think I’d like to finish 化物語 | L31, ラブひな | L23, はちゅねミクの日常ろいぱら! | L25, 名探偵コナン｜L27, and 小林さんちのメイドラゴン｜L26, along with anything I only have 1-2 volumes of. Those are all series that I kinda want to finish and then probably sell. I try to only keep things that I think I’ll want to revisit or really like the art of or want to own the full series of, and other than kobayashi I’m pretty sure I will not be keeping these or buying more volumes of the incomplete ones.
