According to a Game Shokunin Vol. 1 interview with game's enemy programmer Yasuhiko Fujii, before the boss fight against Draygon, the player will encounter a group of Evir enemies that do a little "dance". Their movements actually spell out the words "Keiko Love" in English, referring to a girl Fujii dated at the time named Keiko. He was busy with work and couldn't make time for her, so when everyone in the office was asleep at night, he snuck this Easter egg into the game. Fujii recalled that the Evir dance was never written in the game's planning documents, and that his heart was racing fast as he coded it out of fear that it would be discovered, but no one on the team's staff ever found it.
