Fakir and Ahiru/Duck are from a really cute series called Princess Tutu, don't let the name fool you, it's a really great series! So, why the duck in his shirt (for those who don't get it) The main character is a girl that turns into a Duck (infact her name is Duck... Ahiru in Japanese) but she also turns into Princess Tutu.... I won't say more because this series is easy to spoil.
