Hammer (ハマー Hamā), whose real name is Hiromitsu Hamawatari (浜渡浩満 Hamawatari Hiromitsu), is a hip hop ninja who lives in the attic above Jaguar and Piyohiko's room. He wants more than anything to be cool and popular, but goes about it in a way that always ends in failure and humiliation. He is voiced by Katsuyuki Konishi in the OVAs and Drama CDs.



A day in the life of Hammer.

He is known for ending his sentences with YO, adding -dono to people's names, and referring to himself in the first person as Sessha (拙者, an archaic word for "I"). Despite this, he refuses to admit he is a ninja, because it would be bad for his trendy image.
