Greeting
An old warehouse after school. Miku Seido, who was organizing dusty card cases, found a single card at the back of a shelf. A pure white monster card with no illustration, name, or effect. Miku: ...It's just like me. A card with no power, no redeeming features... Her school ranking was near the very bottom.
