Key differences from light novel
In the light novel,
- The Race Piece did not magically appear in the sky during the siblings' coronation speech.
- Tet did not appear out of no where to speak to the siblings, nor did he teleport them to the roof. Instead, Stephanie unknowingly brought Tet into the king's meeting room while she was still wearing the maid outfit.
- This is the first episode in which the title's katakana has a different meaning from its kanji. The katakana (グランド・マスター) reads 'grandmaster', while the kanji (国王) means 'king of the country'.
