reika's manga / #Revenge(63)

Yeon-Woo has a twin brother who has been missing for years. Their sick mother ends up dying and leaves him alone. He suddenly receives a mail informing him that his bro had been alive all those years doing adventures in a game like world. At first for medicine but he loses track of that goal somewhere along the way until he loses all his battle companions in that world and is backstabbed and killed by them. Yeon-Woo devotes his life to avenge his brothers death and finds the world his brother was talking about. Now all that's left is to find the assholes.

Amamiya, Hiroto died during a ferry trip in Japan and so did all of his classmates and the crew. They're all given a chance to reincarnate into a different world called Origin by a shitty god named Rodcorte and they'd all be given cheat skills. Unfortunately there was another boy with a similar name as MC, fucking Amemiya, Hiroto, and he was accidentally given all of MC's amazing cheat skills so MC instead gets a shitty life as a lab rat for death magic and ends up getting killed by his classmates who were clueless shits. Rodcorte tells MC after his death in his third horrible reincarnation, he'd bring MC back to the normal cycle of life. So he reincarnates MC again this time in lambda, whose name is now Vandalieu, a half vamp half dark elf. His mother ends up murdered and Vandalieu promises to get his revenge not only for those who killed his family, but also revenge to those who were involved with killing him in Origin including the god Rodcorte.
