In order to hide that damaged part of yourself, it takes strength. But I don't have that kind of strength, in all honesty. Feeling like I might have that strength is somehow painful, lonely, and laughable. In this world, there are many people who are lacking for something but don't know what it is and can still continue to live. However, people who think "I can't continue this way," can become duelists. The duels at Ohtori Academy were created for that purpose, for those who have the intense will to bury that part of themselves. It may be impossible, but it's a game that humans who fight to attain something can solely take part in.
