For those of you who don't know, this drawing is a pseudo-reference to Ultraman Leo. As you can see here, Aguri-chan is holding a crutch, much like how Moroboshi Dan/Ultraseven has a crutch, after being injured at the start of the series. And she also has a rather strict attitude, also like Dan or rather, Seven.

There's not much I could say about it, that's all I (kinda) know. I hope this comment clears some things up for you.
And apologies if I got some things wrong, just let me know. I'm not really that familiar with Precure, than I am with Ultraman.
