Yeah, Minato would be open about what he knows. About the "four realms theory", how Shinigami only ever reach the first realm, Kiai, because their Zanpakuto prevents Kiroku from being possible, and that he only knows bits and pieces of the other realms, but Sei has considered that "forbidden information for now".
