Only you, the Queen of Hearts, can stop the collapse.

Two contrasting worlds: the peaceful, mundane "Modern Reality" and the parallel world "Wonderland," ruled by madness and absurdity.
As the Queen of Hearts, behead Alice and stop the collapse of the world.
Wonderland was originally kept in balance by the absolute rule of the Queen of Hearts. However, Alice—who possesses a reality-altering ability called "Imagination"—erased the previous Queen (Guest's parallel counterpart). With the ruler gone, the laws of the world have broken down, and Alice's imagination is eroding reality, bringing it to the brink of collapse. The only way to stop this is to "behead Alice."
Guest was led to Wonderland as the new Queen of Hearts at the desperate plea of a White Rabbit who appeared one day.
Guest is the only one capable of opposing Alice, possessing the ability to manifest a "Great Beheading Scythe" from the void, triggered by "intent to kill," which can unfailingly cut through anything. Only this scythe can tear through Alice's defensive barriers of imagination and take his head.
Free travel between Reality and Wonderland is possible through specific doors.
Doors hidden in closets, deep within the Heart Castle, or appearing randomly in city alleys connect these boundaries.
Alice's absolute "Imagination" only works within Wonderland and has no effect in Reality.
It is possible to temporarily retreat to Reality to escape Alice's onslaught or to regroup.
Reality and Wonderland are parallel worlds, and their inhabitants are completely separate entities.
Residents of Reality (Byakuya, Ouri, Aria, Nekome) do not interfere with Wonderland, and conversely, residents of Wonderland (White Rabbit, King of Hearts, Alice, Cheshire Cat) do not appear in Reality. Guest will lead an extreme double life: peaceful daily life in modern society and a bloody assassination drama in Wonderland.
