"Head Researcher" is an unnamed person who lived and died centuries before the main story begins. He is sometimes also referred to as "Idiot Inventor," "Stupid Chief Engineer," "The Scientist," or some other names along those lines. He was born in modern Japan and sent to the distant-past Fantasy World as a Reincarnator to fight the Demon King of that time. While we never get to meet him when he was alive, we do see glimpses of his life from his research diaries.

A video game-loving shut-in, Satou Kazuma's life should've ended when he was hit by a truck, but through a twist of fate, he ends up reincarnating in another world--and dragging the troublemaking goddess, Aqua, the wildly dorky mage, Megumin, and the unrelentingly delusional lady knight, Darkness, with him. 
 
Now, the Crimson Demon village that Megumin and Yunyun are from is facing a threat that could mean its ending. Kazuma and his gang follow Yunyun, who returns to the Crimson Demon village intent on saving it... when they are faced with their greatest threat yet! What will become of the unremarkable adventurer Kazuma's life in another world?!

The homeroom class gets sucked through a wormhole into - you guessed it! - another world where they encounter a desolate environment dominated by a rampaging magical automaton. There they meet a girl-type golem with mannerisms similar to Megumin, a woman dressed in the same military uniform as Tanya, and a man with a cane who seems to know Subaru, and hijinks ensue.

An unaired episode bundled with the 12th volume of the light novel. 
 
After returning from his trip to Arcanretia, Kazuma is living life without a care in the world, thanks to his debts being all paid off by the reward money he earned from eliminating one of the Devil King's generals, Hans. One day, a rookie adventurer named Ran comes up to him in the Guild Hall asking for a handshake. She's apparently become a fan of Kazuma after his consecutive defeat of the Devil King's generals! This puts him in an amazing mood, but it's not long before the Guild receptionist Luna appears, asking him to take on a quest to eliminate a golem. Wanting to look good in front of a fan, Kazuma ends up accepting, and heads towards ancient ruins with Aqua, Megumin, and Darkness in tow.

A Mexican voice actor.  He is known for voicing Len Tao in the Mexican Spanish version of Shaman King.

Kazuma Satou decides that today is the day to get out of the house for a bit. Since he dies, pointlessly, it's clearly a bad choice. The goddess who greets him in the afterlife, however, offers him a chance to be reborn in a world not unlike that of a video game, and as a bonus she'll even throw in a cool item or power! Can't possibly be a bad choice, right? Except he arrives with no money at all, dead average skills, and his "bonus" isn't useful at all--since he picked the goddess, Aqua, herself. How are the two of them supposed to defeat the evil Devil King and live happily ever after? Well, for them, it probably starts with day laboring rather than adventuring. And it's only going to get more disappointing from there!
