Robotics;Notes

A Robotics;Notes Christmas special released as part of the Science Adventure Series 5 Years Jubilee.

Chaos;Head's story is set in the year of 2008 in Shibuya and is centered around Takumi Nishijou, a high school student at the private Suimei Academy, and some strange events that have occurred recently in the Shibuya area. Two events have occurred so far and is being referenced by the media and the public at large as being New Generation events. The first event named "Group Dive" occurred on September 7th with five high school students jumping to their deaths off of a high tower. The second event occurred on September 19th wherein a male was found dead with a thirty-two week old fetus incised within his abdomen. The story begins on September 28th with Takumi talking to an online friend named Grim. Grim has to provide Takumi with the background about the recent New Generation events since Takumi is not interested local or international news. A person named Shōgun joins the chatroom though he does not say a word until Grim has left the chatroom. Shōgun confronts Takumi and presents him with a barrage of image links that depicts a very gruesome murder. The next day, as Takumi was heading home after spending the afternoon at an Internet cafe, he comes across the same scene that he witnessed yesterday in Shōgun's pictures. He runs away from the crime scene screaming, but not before meeting a pink-haired girl there covered in blood and wearing Suimei Academy's uniform. The story progresses from here with Takumi trying to avoid getting involved with Shōgun and other New Generation events as he is slowly caught in a grander scheme's wheels of motion.

An alternate story of "Robotics Notes" centering on Frau's route. In 2019, childhood friends Yashio Kaito and Senomiya Akiho are together in their high school's robotics club, but it is in danger of being abolished. Akiho wants to preserve the club, as she feels like it is her last link to her older sister, a roboticist. Akiho has only Kaito to rely on, but he's more interested in the game "Kill Ballad Online." It turns out, though, that Kaito's obsession with Kill Ballad may come in handy for their robotics club, and there are other allies they'll meet along the way!

The story detailing the past of Senomiya Misaki, elder sister to the Robotics;Notes heroine Senomiya Akiho.

The cast of 5pb's Robotics;Notes adapted into the 4-koma format. The science may be negative but the antics are decidedly silly.
