Trivia

According to Minoru, they have 78 of the 101 Chemys.
The village is named Kokonotsu Village (九ツ村) which means Ninth Village. Maybe a part of the 1/9 paradigm throughout this series like in Gotchard's card numbers when transforming or Houtarou or Rinne's family names.
Kajiki calls himself Pandora Kajiki in this arc. Maybe a nod to Sancho Panza who was the sidekick to Don Quixote?
80 degrees Celsius is 176 degrees Fahrenheit
In Japanese the planets are written with elemental kanji. So when Hoshino is calling out water, wood, metal, earth, their respective planets are Mercury, Jupiter, Venus, and Saturn. Fire is Mars which joins last.
- Hoshino refers to fire as the fifth element, which might be a nod to the movie of the same name.
