>>yamato nadeshiko shichi henge(the wallflower), episode 3. kyohei(tall, blond, hot) gets kidnapped.
>>kyo kara maoh, episode 51. yuri(blond, cute) gets kidnapped.
>>zombie loan, episode 8. tachibana(cool, i guess) gets kidnapped.
>>kuroshitsuji(black butler), episode 2. ciel(cute?) gets kidnapped.
