Trivia / The World Ends With You: Espoir De Vie

• Inspiration for the Work: The author states that she was inspired by Infinity Train: Blossoming Trail, not only making a reference to it (the fashion brand Lotus Rouge) and also planning on making her own story in the Infinity Train: Blossomverse staring Professor Sycamore. That story eventually becomes Infinity Train: Seeker of Crocus.
• What Could Have Been: Chapter 5's Boss Noise was originally a Luxray but then the author remembered that Sword and Shield was out and swapped it with Boltund. By coincidence this was updated around the same time that Infinity Train: Voyage of Wisteria (the sequel to Infinity Train: Blossoming Trail which the author is a fan of) showed Chloe's Yamper evolving into Boltund.
