I do not own neither Bleach, Dies Irae, Highschool DxD nor Honkai Impact 3rd.) Hyde Eckhart was just your average college student. Having reached the age of twenty years old, he was going to transfer to one of his hometown's universities. However, all of that came to an abrupt end with his sudden death. As cruel as fate may have seemed... it has other plans in store for him. Right after his unfortunate demise, Hyde has been chosen as the "main character" of a certain serpent's grand opera. Now finding himself reborn in a chaotic world ridden danger in every corner, Hyde Eckhart must survive in his new home. All the while, he also must prepare for the fated day when the Longinus Dreizehn Orden begins their invasion... "Come, gather and bear witness to my opera, now in the making. Its script is the height of cliché, I am forced to admit. And yet... Its actors are of the finest fold; beyond exquisite. Thus I believe you will find it... enthralling."
