I felt a little disappointed by the 2nd season due to the science taking a back seat to mediocre action, but this got the show back on track.
The new character, Ryuusui, was really interesting, and he added some pretty cool ideas into the world. The first thing the former multi-millionaire does after being stuck in stone for almost 3000 years is immediately create money and an economy. It's just great lol.
The rest of the characters were as entertaining as ever, and the science was just as good as it was in the first season. Just a super fun hour of anime, and I can't wait for more.
If the 3rd season is anything like this, it's going to be very good. I'm excited.
