You're certainly not the only one around here. In fact, we've got a whole topic dedicated to Toaru. I can't really speak for people reading both, though. Heavy Object doesn't seem acclaimed enough for me to sink my time into it where there are so many other light novels I could be reading. I'd be curious to hear more from the people reading it in the light novel topic if anyone cares to write about it.
I'm kinda obligated to have actual content in my post here so here we go.
I don't have much feeling for this season so far, granted it's early on and most of what I'm watching is throwaway garbage with @Bonecuss. One Punch Man has been fun so far but still hasn't really done anything to make me too interested. I don't know where the story is heading but it'd be nice to see it go somewhere beyond its current comedy state. I get that it's got deeper overtones and whatnot but I can't help preferring shows with a more tangible overall plot. It's still really early on so I'm not at all worried, and I've got faith the show will ratchet up as the weeks go by. Very solid stuff, but doesn't feel exceptional just yet.
Owari no Seraph is probably more meh than it was last season. I didn't expect anything less really but none of the characters feel compelling and Yuu isn't an edgemaster anymore so I can't even poke fun at that. True to form the opening song just feels misplaced against the overall tone and pacing of the animation. Also keeping with tradition the ending is actually pretty cool, although I prefer the one from the first season by a good margin. They'd need to do something damn impressive if they want to regain my interest, but from the way the story and characters appear to be shaping up I'm rather skeptical of that happening.
I'm a week behind right now but the only other show I'm watching worth commenting on is Rakudai Kishi no Cavalry. Not because it's anything remarkable or even worth watching, but the 4th episode at least had me rather interested for something that I had absolutely no expectations for. Fight was pretty entertaining (albeit cliche) and the ending scene threw me for a bit of a loop given how it broke one of the key rules of generic combat high school harem light novel adaptation trash, namely that the romance remains stagnant to enable the protagonist's shitty harem. Of course the show is still pretty mediocre, and I don't know where it's taking this romance but given how @Bonecuss and I have watched a decent amount of this trash together by now this is perhaps the first time I've actually had a show like this exceed my expectations. Then again I watch shows like this with zero expectations so just about the only direction my opinion can go is up. Regardless of what happens I'm rather interested to watch more.
So yeah, that's about it. Planning on adding Subete ga F ni Naru to my stack whenever I find the time, but other than that nothing seems to have stood out too much.
