Edit: Also, Magical Girl's speech gradually gets more and more feminine as the panels progress (from Page 1 of this arc to Page 3), though it's a bit hard to indicate this in the translation.
She's changing from "the guy's personality but changed due to magical sparkly bullshit" into an actual separate personality.
And the separate personality is a yandere, if that close-up on the left panel is any indicator.
edit: Is this really in the MBU?
Whoooops, messed up when copying tags. Had a template of sorts for Ishiyumi comics, and forgot to take off the MBU tag. Fixed. Thanks for bringing this up.

You mean... a mere side effect becomes a full-blown personality!? Like, a decent guy turned violent when drunk; it stops when the alcohol effect is gone. But if the drunk act persists even without alcohol...
That's... pretty scary, I admit. Even though it's played for laughs here.
Evil monstrosities are likely going to continue popping up regardless.
—isn't strictly necessary,
is it?
...I've found it.
The Heartthrobs of Love are the source of a Magical Girl's power, pico!☆
Yes, that's right.
If so, staying in this form will let me become stronger, probably...
A good reason not to go back—
And with all said, I get to use magic in this form, so it's more convenient anyhow.
If so, even should they start getting worried over my original self disappearing—can't I just magic that problem away anyway?
