Puzzled Memories: Underworld

An unforeseeable catastrophe claimed the life of Inaba Shig, a 23-year-old martial artist genius. After being reborn into a different universe, he was offered a second chance to remake his life. However, this came at the cost of losing all of his memories from his previous life. He was able to reclaim some of his memories from his previous life as a result of the Awakening. But he wasn't satisfied with just that, so now Inaba, or should I say, Solomon, is now looking for a means to reclaim all of his memories.
