L and Beyond Birthday never diid get along but it's only going to get worse between them. THe two nearly identical boys have always had an extremely complicated love/hate relationship, but when the two realize they both are after the exact same person: A, next in line to take L's place if something should ever befall him in his line of work.

When L and BB notice eachother's uncanny interest in A, the new competition begins. The Winner gets A, and The Loser just might lose it all. THe outcome is unclear, but it's obvious enough: there are only two options, this will either tear the three farther aprt or bring them all together in the end.
