Tsubokura, Rin

壷府リン

Rin Tsubokura is a Shinigami who bears a strong resemblance to Hanatarou Yamada, the 7th Seat of the 4th Division. He almost always displays an expression of distress or preoccupation and, oddly, has a small pigtail on the front side of his hair. He works as a researcher at the Shinigami Research and Development Institute and has a fondness for candy and sweets. He is somewhat clumsy, as demonstrated during a Shinigami Golden Cup event where he fell onto sweets, yet they remained unbreakable. In an episode where he had to help an earth-bound soul make a cake for his mother, he immediately offered his assistance despite protests from Yumichika Ayasegawa. His gender was confirmed as male in the Colorful Bootleg book, although Viz's English translations refer to him as female. His love of candy and sweets causes significant trouble in the DS game Dark Souls, leading to a Mod Soul named 'Kai' taking his form.
He is mostly assigned to easy missions, such as when he was sent to deliver Ikkaku's molars. However, he stepped on them and then attached a note reading: "These molars are invisible for Idiots".
