I see that one of the people that the team talks to after they come back to life is one of the first team's old members, but the squinty eyed person behind her also seems familiar but I can't pinpoint who she is. Does anyone know?
The beard guy made soap by a chemical reaction called Saponification.
Saponification is:

Didn't expect organic chemistry to come in handy here
2nd opponent and person who beat hibiki are both from kengan. The first was the mc, second was a guy who could see through all of his opponent's moves.
