Doraemon's Hand

Doraemon's born on September 3, 2112... so 102 years to go for technology to advance...

Motto To Love-Ru -Trouble- 03

Part 1 - Yui: Yui's sick so Rito goes to her home to deliver class notes and things go a little wild...

Yui's actually a younger sister like Mikan...

Part 2 - Run: One day, Rito puts on a pair of glasses which lets him see through people's clothing...

... and the setting can even be adjusted so the user can see everyone naked...

Run later has another pair of glasses that she wants Rito to put on but accidentally changes her gender... which leads to the awesome view in the end...

Part 3 - Riko: Riko's having a date with Saruyama...

But they're doing nothing except watching love movies... and the transforming effect ends before Saruyama's confession at the end of the day.

"So... Rito loves cross dressing..."
