Kind of a repetitive episode where Suzuha and Daru are trying to recruit Maho to help them build a time machine.
The only novel thing was Kagari being a brainwashed spy. And the new hidden persona comes to light - the doctor who's probably the one doing all the experiments on children, brainwashing them.
I feel like this show suffers from repetitiveness just like the original one. However, the original had more charm and humor to make up for it. This one doesn't.
