Kicked out by his family and wandering the streets, an unemployed 34-year-old shut-in thinks he’s hit rock-bottom—just as he’s hit and killed by a speeding truck! Awakening to find himself reborn as an infant in a world of swords and sorcery, but with the memories of his first life intact, Rudeus Greyrat is determined not to repeat his past mistakes. He’s going to make the most of this reincarnation as he sets off on the adventure of a second lifetime!

Beautiful and brilliant sorcerer girls just can't have nice things, huh? All I wanted to do was swipe a little bit of bandit treasure. Now suddenly I'm being chased around by icky trolls, nasty demons, mean mummies, and brooding golem bad boys. And for what? A tiny little artifact that can bring about the end of the world? Hah! I'll show them there's a reason you don't cross Lina Inverse...

Takasu Ryuuji might look like a thug, but he's actually a nice guy. Making friends when you've got an unintentionally scary face is tough--and don't even get him started on girlfriends. But with his secret crush in his class, the start of his second year of high school is off to a good start...until he crosses paths with Aisaka Taiga. Beautiful, frightening, and not quite five feet tall, the girl known as the palmtop tiger is the one person in school even scarier than Ryuuji himself--and he's just made the mistake of making her very, very angry.

One day, the life of middle-aged Japanese businessman Ryoma Takebayashi came to a rather sudden and disappointing end. Ryoma had never had a blessed life, but after his death, three great gods sought his cooperation and reincarnated him as a child in another world with swords and magic!

Sagara Sousuke isn't your typical high school student. He reads military enthusiast magazines; he responds to questions with "affirmative;" he brings grenades to school in his bag. Though everyone at school takes him for a hopeless military geek, Chidori Kaname thinks there might be something more to him. When their plane is hijacked in the middle of a field trip, Kaname's instincts will prove correct: Sousuke is an elite, mech-piloting mercenary... and he's here to protect her!
