Sentomaru

Sentoumaru is the captain of the Marines' Science Unit and bodyguard of Vegapunk.

Relationships
Sentourmaru refers to Kizaru as "Uncle" (Kizaru-jii-san), although the Japanese term used does not mean they are family, but rather the pair are on a high level of respect (despite Sentoumaru shouting at Kizaru for using the wrong Den Den Mushi).

History
Sentoumaru was first seen on top of a building when Dias attempted to escape his slavery from his Tenryuubito enslavers, although not introduced then. Sentoumaru had been disappointed that Dias was not a big named pirate.

When Kizaru arrives on the island he attempts to look for his subordinate but unsuccessfully contacts Sentoumaru. Later Sentourmaru is seen on top of a building wondering where Uncle Kizaru got to since the fight had already started. When Sentoumaru finally contacted Kizaru, Kizaru was scolded by Sentoumaru for trying to use a Black Den Den Mushi instead of his Baby Den Den Mushi.

Trivia

 * Sentoumaru's name contains the kanji for "peach" in reference to the Japanese story Momotaro, from which the admiral names are also derived. His design is also similar to that of the Japanese folklore hero Kintarō (also known as samurai Sakata no Kintoki), who was notable for carrying a massive axe and his raising wrestling bears. (possibly showing his close connection to the Kuma-clone Pacifista)
