Hina-sensei, is that your latest manga? Or are you signing autographs?

Nope... I was thinking of some vague ideas for my Magical Girl Hina costume

Ahh, your next costume! ...Wait, what? But this isn't the one you were going to wear, is it Hina?

It's the post-transformation version! If it's good enough, they said we can actually use it... For now, I was thinking that I'd have some mysterious wings sprout!

Oh, wings growing, right-♪ Then, no reason other parts of you can't grow too

You could make it just a little sexier! Like, exaggerating the chest area somewhat

Ahh! How could I forget that classic cliche...

Then how about this! Thighs like boom, and bellybutton like bang...♪ At this level, I expect Sarina-san to run in and say 'Nice Sexy♪'...

Really getting into it

Ah, Producer-san! Hina-sensei's second half of the costume is coming along very nicely♪

She ended up redoing it later.
