It's cold, it's dark, work is every day. And yet there is time for anime.
Manga
Beyond continuing GTO at a glacial pace, as well as keeping up with Shibuya Near Family and Wasteful Days of High School Girls + Gekkan-Shoujo Nozaki Kun whenever updates release, I have picked up Inari, Konkon, Koi Iroha. It's short, it's fun. I'm pretty early into the story to comment more.
Anime
I have finished Monogatari: Second Season, and the Kaiki arc is just fantastic. It's another high in a series that I have both underestimated and feel that it does live to its questionable reputation. Onto the next series, which is... uh... Hanamonogatari?
One Outs is a gambling sports anime that has been recommended to me for a while, and it is decent so far. The MC is pretty un-Kaiji like, and more your average extremely confident gambling genius.
I've watched Vivy: Fluorite Eye's Song and I enjoyed it quite a bit. It's somewhat style over substance, but it is refreshing in a sea of formulatic slop. I remember the ending having a bit of controversy surrounding it. I thought it was tragic. The post-credit scene did cheapen that though.
Cardcaptor Sakura keeps being fun and cozy.
I have also resumed Sailor Moon, from Season S. It's still good old Sailor Moon.
Millennium Actress was a pretty good movie, aided by the soundtrack of the excellent Susumu Hirasawa. I felt like I missed half of the appeal of the movie by not being that familiar with what was most likely 1930s to early 1970s Japanese cinema.

Oops, all manga update on my end.
Opus Little 19 chapter meta commentary on artists and their work by Satoshi Kon. A lot of this felt familiar/reused with the anime production episode of Paranoia Agent.
Chainsaw Man (up to vol 12) I'm not usually one for the trendy battle shounen series of the moment, but I like this one a lot. I just started the second big arc, so I'm just waiting to pick up the next books to see where this goes. This genre works a lot better for me as a comic, so I'll probably branch out to whatever my library has.
Dororo Peak edgy Tezuka. I'm about halfway through this one, but I'm enjoying it a lot. I've been a fan of chanbara action since I was a kid, and this one is super weird since everyone looks like a little blorbo. I'll probably get into Astro Boy or Buddha or something else soonish.
