Asahi in Wonderland

Asahi in Wonderland is Astral Academy's 9th chapter. Based off of Alice in Wonderland, the floor breaks and causes Asahi and Dorm A to fall down into a labyrinth called "Wonderland". Asahi, Sayu, Namida, and Zenya must explore until they eventually find Kuroi.

Plot
The day starts as normal, Asahi being nervous about his alchemy class since he couldn't quite catch on to yesterday's lesson. He hears Kosui talking to Rune (Dorm D's dorm leader) about something until they feel the floor shake. Sayu yelps and grabs onto Asahi's arm. Sounds of panic are heard as the floor eventually falls apart, causing all of the students to fall.

They wake up in a place dubbed "Wonderland". It takes form as a maze, accompanied with occasional homages to Alice in Wonderland. No other person is in sight other than Sayu, Namida, and Zenya, so the four of them travel together to try and find an escape. They will fight off enemies and solve puzzles until they find the exit.

Near the end of the chapter, they find Kuroi, standing in front of a locked chest. This was right when Miyasaza starts his ritual, unnerving them. Namida says that she didn't expect less from an executioner's son. When Asahi asked her to elaborate, she whispers to him about the documents discovered in Chapter 8. Suddenly, there's a blinding flash of light, and Chapter 10 begins.
