What's the order of reading these series? I'm confused by the spoiler in the encyclopedia.
Tsubasa Chronicle and April 1st Supernatural Event Book were both manga and light novel series created by the same author, Oda Kumu. The stories took place in the same fictional world. Therefore, the order of viewing these works was not fixed. It could be chosen according to one's personal preferences and interests. However, generally speaking, it would be easier to understand if you read Wing's Chronicle and April 1st Paranormal Event Book first before reading April 1st Paranormal Event Book. The Age of Wings was a fantasy novel, while April 1st was a horror and suspense novel. Therefore, reading The Tsubasa Chronicles first would allow one to better understand the fantasy elements, and then reading April 1st Paranormal would allow one to better understand the horror and suspense elements. Of course, these works all had their own unique characteristics and plots. They could choose the order of viewing according to their own preferences and interests.
