Voltage Fighter Gowcaizer - Brider (Neo Geo MVS) 超人学園ゴウカイザーブライダー

Ikki's family comes from a long line of renowned and charismatic bancho, a sort of rowdy male cheerleader who leads fans in the E Area of the school. One night, while he was returning home from practice, he saw a puppy carelessly run into the road. Seeing a car coming towards the unknowing canine, Ikki dove for it and saved them both by slamming into the guardrail on the other side. He lost consciousness after his feat.

When he woke up, his limbs were bound to a bed and had a mysterious man covered in flames stood next to him. The mysterious man said that Ikki was a worthy subject and promised power to reinvent himself should the boy remain loyal to him. Two men tried to assault him, but Ikki was able to spring loose and break through the window. Cutting through branches and glass, he was able to escape from the suspicious group.

Walking through the sudden rainstorm that followed, he found the wounded puppy he saved and decided to live together with it. Feeling humiliated at seeing his new form, Ikki could not stop his tears at the new Brider form he was forced to wear. He wants to defeat the school principle to somehow rid himself of his ugly new form (from https://snk.fandom.com/wiki/Brider).
