Unbold Amgaa was born on 18 August 1988 in Ulan Bator Mongolia. His father was a successful Mongolian wrestler with a rank the equivalent of sekiwake.
His highest rank is maegashira 15. Then yokozuna Asashōryū noticed his talent and word got to the head of Shikoroyama stable, the former Terao, who had come scouting to Mongolia. Amgaa accepted an invitation to come to Japan to enter sumo and while still a teenager he joined said Shikoroyama stable, taking the ring name (shikona) Seiro, meaning "blue wolf".
He competed in jonidan for the next ten tournaments, recording more wins than losses (kachi-koshi) on six occasions before being promoted to the sandanme division for the July tournament in Nagoya in July 2007.
After four consecutive kachi-koshi he was promoted to the makushita division in March 2008 but dropped to sandanme after losing four of his seven bouts. In the May tournament of 2009 he was unbeaten in seven contests, taking the championship in that division, securing his second promotion to makushita.
Injury problems in early 2010 saw him relegated briefly to sandanme but he returned to makushita for the Nagoya tournament in July. After another three years in the division, Seiro was promoted to jūryō rank in July 2013.
In the May 2014, he took part in a four-man playoff for the jūryō championship which would eventually go to Ichinojō.
In the first three tournaments of 2015, Seirō made kachi-koshi, recording nine wins in January, eight in March and eight in May to earn him promotion to the makuuchi division. In his first appearance in sumo"s top division he was ranked maegashira 15 for the Nagoya tournament in July 2015. After two losing results he was demoted to jūryō for November and recorded eight wins to maintain a position near the top of the second division.
Seirō favours a left hand outside, right hand inside grip on his opponent"s belt.
He has employed a wide variety of winning techniques (kimarite) but his most common is yorikiri or force-out which accounts for almost 30% of his wins. He also makes frequent use of uwatenage (outer arm throw) and yoritaoshi (front crush-out).
After a decade of competing in the lower ranks of sumo he reached the top division for the first time in 2015. Seirō made his debut as a 17-year-old in September 2005 when he won five of his seven bouts in the lowest jonokuchi division and was immediately promoted to jonidan. On his makuuchi debut Seirō won seven of his first thirteen bouts but lost to Yoshikaze and Homarefuji on the last two days to end with a losing record (make-koshi) of 7-8, which nevertheless enabled him to maintain his place in the top division. He again recorded a 7-8 result in September: although he won seven of his twelve matches against makuuchi opposition he lost all three of his contests against jūryō wrestlers. In January he won his first five matches to head the jūryō division, but won only two of his subsequent bouts to end the tournament on 7-8.
