Esports organization Sengoku Gaming has announced the departure of Zerost from its streaming roster. After four years with the team, including competing in League of Legends and VALORANT, his contract has come to an end.

Zerost esports career began in the early 2010s. In League of Legends, he played for top Japanese teams, including DetonatioN Gaming, BlackEye, Burning Core, Sengoku Gaming, V3, and Rascal Jester. With DetonatioN Gaming, he won the LJL Spring 2016 championship and finished second in LJL Spring 2017.

In January 2020, he joined Sengoku Gaming as a streamer but transitioned to competitive VALORANT in May. With the team, he became the runner-up of the VALORANT Mildom Masters. After leaving in 2021, he played for CYCLOPS athlete gaming and BLUE BEES.

Zerost returned to Sengoku Gaming in May 2022, playing as an Initiator and Sentinel. He helped the team reach the VCT 2022 Japan Stage 2 playoffs, finishing in 8th place. In November of the same year, he retired from professional play and refocused on streaming.

Announcing his departure from Sengoku Gaming, Zerost jokingly commented on X:

I don't even know how many years I've been with the team, including my time as a player. They helped me a lot, especially after I started streaming. And I'm leaving because the owner plays LoL too badly.
