I don't feel anything from any of the newbies. Not talking about Undead, but the rest. Agravity has had some chapter that made me laugh but keeps having 0 attraction to me, and Mitama since the beginning has been even more unattractive. Situations and reactions keep being the same, and meh, I just can't get to properly enjoy them. ZIPMAN has become one of the most basic series from them all even if it's the only one that's not comedy, and its action and epicness just feels kinda childish. As for Yozakura, am I the only one that gets Samon's vibes from it? As in structure. I feel like I should have never thought about it as an action series, since its main focus for 20 chapters already have been pure episodic comedy. Which is not bad, but eh.
I don't know, I don't see a single one of them sticking. Anyway, good luck for them with sales. If I had to choose two, I'd probably go with Yozakura going the episodic route instead of trying edgy action and Agravity Boys since I have laughed with it a bit more than with Mitama. Such a shame I can see most of them dying while they keep Samurai 8 x d.
