The Flash Adventurer

After dying in an accident, a young man is reincarnated in a world of swords and magic as Arte, the second son of a powerful marquis. His new life seems like a dream come true, surrounded by a warm and loving family. But everything changes during the sacred ceremony where he is granted magic.

He receives a mysterious, unique power called [Light], a skill immediately dismissed by everyone as a useless dud. Just as he faces their scorn, memories of his past life come rushing back. With knowledge from his former world, Arte alone understands the hidden, extraordinary potential of his magic. Now, by applying the wisdom of his past, can he transform a "dud" into the strongest magic of all!?
