Rin Tsubokura

is a Shinigami who bears a strong resemblance to the 7th Seat of the 4th Division Hanatarō Yamada.

He is almost always showing a face of distress or preoccupation.

He has (oddly) a small pigtail done in his front side of his hair.

He is a researcher of the Shinigami Research and Development Institute and has a fondness for candy and sweets. He is a bit clumsy, as shown in a Shinigami golden cup where he fell on the sweets, but they were unbreakable. During one episode which he has to help an earth-bound soul to make a cake for his mother, he immediately offered his help apart from protests from Yumichika Ayasegawa.

He is mostly sent to easy missions, just like when he was sent to give Ikkaku his molars. Though he stepped on them, he put on a note saying, "These molars are invisible for idiots".
