"Everyone, Bonne lecture. It's me, Tassel. There was once a young man who died and came back to life. On his path to resurrecting himself, he bonded with a variety of heroes and saved the world with many friends by his side. While on this corner, we have a young man who fights with books and sacred swords in order to protect the world. And now, these two tales fated to be entangled. I simply cannot contain my excitement!" --Tassel.
