Raiden is a world class athlete known for his strength. Being one of the greatest sumo wrestlers on the planet, with a record of over 700 consecutive wins, his "strength that surpasses knowledge" is admired all around the world. As such he has been offered countless times by the Hero Association to be recruited. Disliking the ways of the Association, he harshly rejects each request, no matter how much they offer him.
Instead he chose to, just like Accel to join an organization that plans to overthrow the Hero Association.
