Nice! I was looking if someone knew about the Gochiusa April Fools worlds and mentions it. Funny seeing them integrated in one way or another in the main story by way of dreams and events that add more depth to the characters.
Adding this as a reply to list the April Fools references for others to see.
There's been a few chapters referencing the April Foold worlds.
Ch. 166 (this chapter) is on the "Regene Play Rabbits" from 2020.
Ch. 159 was on "Take Out Blue Bird" from 2022.
The end of Ch. 138 partly references the later "Galaxy Train Rabbit House" from 2023.
Ch. 132 was on "Seven Rabbit Sins" from 2021.
Ch. 114 was "Clockworld Rabbit" from 2019 and partly on "Daydream Show" from 2018.
Vol. 8 Ch. 11 (Ch. 104) was on "Chimame Chronicle" from 2017.
Vol. 7 Ch. 4 (Ch. 83), Vol 6 Ch. 6 (Ch. 71), Vol. 6 Ch.3 (Ch. 68), Vol. 5 Ch. 6 (Ch. 58) are a few of the many chapters that shows Syaro's "Phantom Theif Lapin" from 2017.
I think "Magical Girl Chino" from 2015 has also been referenced at a chapter, but can't find it right now.
It was fun looking back at some chapters from a while back as I noticed the significant improvement in the shading of the color pages between Vol. 10 and Vol. 11 (from Ch. 133) and later that gives as effect that's like glowing.
Its amazing to see how much the art style evolved with earlier volumes look really different than later ones in terms of art style. There's points of significant change around Vol. 2, Vol. 3, Vol. 4, Vol. 6, Vol. 8, Vol. 11.
