Unwavering

Seventeen-year-old Kimura is your average, everyday otaku. However, his life of pulling all-nighters, sleeping in class and gaming is suddenly turned upside down when, in an attempt to save a kid from a car crash, he dies himself. Whilst his life flashes through his eyes, Kimura was given a chance to relive his life. He awoke moments later to find himself reincarnated into a body of a teen in a new unknown fantasy world!
But as if the nightmare couldn't have gotten worse. Whilst everyone was blessed with godlike powers, learning magic and battling techniques, Kimura was stuck with a levelling system, stats worse than of a farmer and one simple Synergist type skill- "Transmutation". 
Plunged into world where the strong trample over the weak, Kimura tries to survive striving to live his life to its fullest. Will he pull through in this dangerous world of monsters and demons with only his survival instincts and wits?
