Keigo Tatewaki (帯刀 啓吾 Tatewaki Keigo?) is a side character from the first Jewelpet series.


Tatewaki is a very serious guy who usually follows orders from the Prime Minister in order to find the Jewel Charms and not let any information leak out. However, he can be unpredictable; sometimes messing up on his work or being annoyed by the Jewelpets themselves. But out of all of those flaws, he is very supportive towards Rinko and and her friends.


Keigo shows knowledge of martial arts in the first episode and is capable of conducting through research as his position in the secret services demands. However, these skills are largely rendered obsolete by the unpredictable nature of the Jewelpets and their magic.


Keigo is the secretary to the Prime Minister and is dispatched by the secret services to deliver the Jewel Pocketbook, entrusted to them by Raku Majo to the person that has Ruby's Jewel Charm. He finds Rinko and is tasked with watching over her progress, as well as finding Diana and Dian so that their plans can be foiled.

Keigo eventually becomes Flora's human partner, after he was afraid of almost letting out the secrets of the Jewelpets themselves.
