There's no man on Earth who doesn't like panties! (Wise saying.) Of course Umio loves panties, too! (Let's make it clear.) Sensei tells him bashfully, "Do you want to see them?" What's going on between those two?! Then she shows up! A mysterious woman who knows about Umanohone's past. And she's got unsurpassable girly-power! To top it all, her amazing power is still rising...? Tsk! Our scouter (yes, the device to measure power in that famous anime!) must be malfunctioning!
