Raitei roughly translates to thunderbolt or thunderclap.
- Thunderbrand shares a resemblance to Amatsu, both of which are modeled after the Seven-Branched Sword or Shichishito (alternatively Nanatsusaya-no-Tachi).
- Unlike the other Heroes' Relics, Thunderbrand can be used thirty times as opposed to twenty, likely because it functions as a brave weapon.
- Additionally, Thunderbrand is the only Relic that is never given to the player as an event.
