■Story Rintato Okabe, commonly known as Okarin is a University student, who is still stuck in *Second-grade Syndrome. He introduces himself as a mad scientist named Kyoma Hououin and he spends most of his time doing odd research with several members of the Future Gadget Laboratory, which is commonly called Lab. They accidentally find an invention, “D-mail,” which can send emails to the past. One day, Okarin finds the lab members busily arranging a celebration party for a newly completed gadget. But, why have they produced a new gadget while Okarin doesn’t know anything about it? The number of lab members has increased from six to eight. It seems that they have changed the past with the D-mail inventions. What’s more, due to the D-mail inventions, the electric bill has gone up immensely. Creating a cash flow problem for the lab. Therefore, in these circumstances the members plan to sell a new gadget to solve this financial difficulty.

*Second-grade Syndrome most commonly appears in the second year of junior high school (around 14years old). Symptoms include extremism, audacious behavior and hyperactivity, similar to mental illness. This syndrome occurs during adolescence.
