Aki Shindachi was a Japanese yakuza who was affiliated with the Kobe-based Kuroha-gumi subsidiary of the Omi Alliance during the 2010s. In December 2012, he and several other hitmen were sent to murder Tatsuo Shinada at the Wyverns Stadium in Nagoya to prevent the Nagoya-gumi from being exposed, but Shinada and Yuki Sawada knocked them out in a brawl on the baseball field.
