Canon
It's all started when Tenko and Oboro met Stain after Stain defeats Ingenium (Tenya's brother, Tensei, not Tenya), Oboro warps to greet him and Stain responds by raising his guard. However, Oboro says they are of similar breed and that Stain may be interested in an offer. Stain warps to the LOV with Tenko and Oboro to discuss joining their ranks. When he questions Tenko's convictions, he's disappointed to find out he's simply trying to destroy anyone he doesn't like. Oboro wishes to step in, but his master orders him to stand aside so that Tenko may learn from the experience. After Stain and Tenko 'fought' each other, Tenko angrily said that he doesn't want Stain to be in LOV and warped Stain back at Hosu, and then releases the nomu's. One of the nomu's are trying to take Izuku after his (,Tenya's and Shoto's) fight Stain and Stain killed the Nomu and saved Izuku. Two days later, the video of it got viral across the Japan, making villains interested in LOV and joining them, and one of them are Shuichi. Shuichi joined the LOV because he thoughts that it would help him to continue with Stain's legacy, Shuichi admires Stain greatly, Shuichi is completely obsessed with the ways of Stain to the point where he copies his clothing and weaponry style, aiming to follow the same ideals as him and make his dreams come true, so when he sees Nomu in Stain's video, he immediately got interested in LOV and joins it.

In the peak of the, Touya tells Shuichi, who was driving the truck to escape the Hassaikai's to stop swerving the truck, but Shuichi retorts Touya, annoyed that he was a problem with the driving skills he learned from gaming as well as further annoyed that attacking a police convoy has nothing to do with creating a true society. Tenko reassures Shuichi that it is a necessary sacrifice, making Shuichi began to doubt his actions but he decided to do as he said. Later, after the League had little benefit from other operations, Shuichi finally lost his patience and began to shout at Tenko that he has little faith in him and his ability to lead the League of Villains. He openly questioned how Tenko and the League would help him bring Stain's goals to fruition, Shuichi observed Tenko's determination to defeat and tame Gigantomachia, he began to respect him as a leader in his own right, without the influence of Stain. He offered his opinion to Tenko during the fight against the, and expressed an urgency in assisting and later rescuing him from the subordinates of the Army and Rikiya. Upon witnessing Tenko's triumphant victory, Shuichi was left in awe of his accomplishments and the enemy bestowing an army upon him.
