Holy crap this arc is boring, frustrating and just way too long.
I would be OK getting to know why Shiki seems so usure of himself, when he clearly isn't dumb, lazy or socially inept... We get it now, it's his mom fucking up his life by being an enormous ball and chain...
If this arc concluded like last chapter, or even this one, that would be fine, but this is clearly being set up to go for a while.
I'll park this manga in "On Hold" for a few months and check back this summer, maybe.
