Great chapter.

Mom (and onee-chan) weren’t worried about how well she might do on a problem on the chalkboard - they wanted to make sure she was enjoying herself with good people who cared about her. And she is.

It’s really impressive how the mangaka’s expanding on things in the serialized version.

IIRC, we did get to see Airu the first time through, but only briefly and in idol mode - we didn’t get even a hint of her background until just now. And the way it played out - slipping into her old delinquent mode just long enough to deal with those guys, then switching to idol mode to win then over as fans - was brilliant.

And the other girl covering Urumin’s eyes was a great touch, and funny to boot.

That was adorable.
