So, after Kubo/Yabuki/shibashi coming back , what author you want to serialize in 2021?
Matsui because he is Matsui
Naoshi Komi because I don't know what will he do and I'm interested what next for him(another romcom? a spokon like the e-sport one? an action with romance?)
Kenta Shinohara because why not, Inagaki is here.
Takamasa Moue, Yusuke Utsumi, Yushin Kuroki, and Gen Osuka are at the top of my lists for mangaka without a previous hit. Rookies who each had one failed series, however I'm confident their next series will be a hit. All four are super talented and their works have a lot of passion/character. Still holding out hopes Moue goes back to Galaxy Gangs for his next serialization.
I'd like to see the Neo:Lation duo return as well. The series had its issues, but I honestly really enjoyed it nearly every week.
Also, even though Yasuki Tanaka had two failures in WSJ it'd be cool if he got another chance in the main mag after having something of a success in Jump+.
I'd like to see Daijoro Nonue again, but given there was a six year gap between both Mutou Black and Last Saiyuuki, both of which were failures I'd wager it's pretty unlikely we'll seen him again this quickly.
With all the older vets returning, I'd be curious to see Kazuki Takahashi trying a new serialization. He did that miniseries not too long ago so clearly he's not completely retired.
I'd also love to see Yoshiyuki Nishi, Toshiaki Iwashiro, Yasuhiro Kano and Ryu Fujisaki try again as well.
Would kill to see Naoki Iwamoto but I haven't heard anything about him since that Jump Vs. oneshot collection years back.
