Skeleton Knight in Another World

The second season of Gaikotsu Kishi-sama, Tadaima Isekai e Odekakechuu .

​Seventeen years ago, Takafumi's uncle fell into a coma, but now he's back like a man risen from his grave. Soon, Takafumi discovers two bizarre things: His uncle treasures video games above all else, and, while comatose, he was actually transported to another world as some heroic guardian! Now, not only does Takafumi have to room with an uncle who is literally magical, he also has to catch the guy up on two decades of history—smartphones, high-speed internet, modern anime tropes…and the traumatic outcome of the '90s console war!

Shiina Kazuya is killed protecting a young girl at a convenience store where he just happened to be at the wrong time. The next thing he knows, he's in the kind of world he has only dreamed about--a world of magic and swords! He has been reincarnated as Cain von Silford, the third son of an aristocratic family, and he quickly grows interested in many things he sees. Then, on his fifth birthday, he's baptized at a church according to tradition... and the gods grant him several divine blessings, along with stats that could only be described as unusual and extraordinary! In his reincarnated life, when it comes to things like battles, romance, and studying, apparently a little overkill is just right?! When he puts in the usual effort to do things punctually and properly, it only gets him in trouble... Thus Cain's chaotic life in another world begins!
