Yasochika Iemura

is the 3rd seat of the 4th Division, and the leader of the first relief team serving under Captain Retsu Unohana. He is also the Vice-President of the Shinigami Men's Association.

Iemura is very vain, likes to act cool, and thinks he will look better without glasses. He was born on a leap day, February 29. His rank is quite high, but since he comes from the weakest division in terms of combat he has to call the other divisions's 3rd seaters with a -sama suffix. He meticulously keeps a diary, which he sometimes defeats the purpose of by narrating what he's writing in it (particularly when lamenting something). He takes direct command of the division like a general. His speedy treatments rival those of the lieutenant, Isane Kotetsu.

Synopsis
He is first shown directing the relief team of the 4th Dvision while being on the front lines him-self. He is shown briefing all the Division's Leiutenants after the 11th Division suffers multiple losses due to injures including 3rd seat Ikkaku Madarame and 5th seat Yumichika Ayasegawa. After most of the Ryoka (Uryū, Chad, Ganju) are taken for medical treatment he is shown docummenting the recent events in Soul Society, while not noticing that he is speaking outloud. Thru the rest of the story he is mostly seen in omake chapters, usally involving both his Division Captain and Leiutenant.
