It's not the translation team who dropped the series. Bunko-sensei's health got too bad to continue it. That's why there were so many gaps between updates at the end, even though it started off as a monthly serialization.
The manga has now picked up from where it dropped off, but we have a new artist: Akiko Kawano. You can read the latest chapter here: https://zerosumonline.com/zerosum/comic/lastame-tts
Oh that's too bad. Thank you for letting me know!
So that's why... I was surprise it say discontinued at Animelist, and jump right here at the comments.
I neeeeeed this to be picked up again. Really love this one
