Following a late-night talk with her beloved brother, high school student Arisa Minase awakens the next day in an unfamiliar land. She is welcomed as "Alice" by twins named Light and Shadow, who voice their relief at Alice's return home. Arisa insists she is not the Alice they refer to, but the peculiar inhabitants of this world remain firm that she is. After encountering the kind yet enigmatic Black Rabbit, she discovers she is confined in a place called Wonderland with no obvious way out. As she adapts to her new reality, Arisa encounters a variety of odd creatures, including the affectionate Cheshire Cat and the lazy dormouse Round. However, Wonderland holds more than what is visible. Every wild personality she now lives with resembles someone from her previous life, yet none of them recognize their former names or connections. Even more bizarre is that time in Wonderland appears static, with each day identical to the previous one. There seems to be no conclusion to this cycle—except for whatever secrets the Black Rabbit is hiding.
