I'm hoping for a season 2. The Vacuum Butt Cannon is deadlier than Goku's Spirit Bomb lol !!
Probably won't be one. The manga was abruptly ended so it's unlikely the publisher will agree to future seasons.
Sorry to break it to you, but season 2 is likely to never happen.
From what I understand the anime did poorly, and to add insult to injury, the manga too got cancelled. To a degree I think the studio making the anime wasn't expecting a season 2 either, hence why they gave us a somewhat satisfying ending.
Likely to never happen. Sucks too because Keijo was my personal "best of the season" anime.
I'll add even more to this. The word in Japan, when the announcement was made that the manga would end, was that the reason for cancellation was "poor reception outside of Japan". It's the only instance I'm aware of that outside licensing was named as the cause for cancellation of a series/IP.
