  Summary

  Yagi Toshinori heads to U.A. to find a suitable inheritor, and maybe settle down away from the big hero life, but ends up finding his own little. Only after handing little Izuku the greatest quirk in the world, of course, but surely he wouldn't regret giving a sensitive, highly emotional, empathetic, and very protective little the power to level cities with the flick of a finger or a tantrum. Right?
