"My Promise to Eichi" (
- Mitsuki makes a comment that the song, "New Future," that she sang at the end of the previous episode is a song that her father wrote. In real life, the song is really by Changin' My Life, Mitsuki's Japanese voice actress Myco's band.
- There are some points in the episode where Meroko's gloves disappear.
- When Meroko transforms into Eichi, she is the same height when she transforms. But when she goes and talks to Mitsuki as Eichi, she is just a bit taller than Mitsuki. Meroko is much more taller than Mitsuki, so if she transformed into Eichi and was still the same size, it would not make sense.
