I will try to make things clearer, because the whole "the hacker made himself into his favorite character" is screwing everyone mindset : forget about the hacker part, it's for flavor text on the playable character, not the Heroic Spirit.

Also, said Heroic Spirit would be summoned as a Caster otherwise and he would have all 3 Noble Phantasms : the riding item, the light guardian spell and the mysterious third skill.
