It has always been the aspiration of the Central Tanegashima High School Robotics Research Club to complete the GunPro1, a fully functioning giant robot. For years, the members of the club have contributed to its progress and it is now Akiho Senomiya's goal to finally make the dream of all the past club members become a reality. However, things are not as easy as they seem as the club lacks the funding for such a huge endeavor. Aside from that, the only other club member, Kaito Yashio, shows no interest in assisting his childhood friend and instead indulges in playing mecha-fighting games on his "PokeCom." As Kaito is in the middle of wasting his days, he receives an indecipherable message and hears a voice that seems to be drowned out by the noise of static. He searches for the source, only to realize that it came from Airi Yukifune, an AI which only exists within the augmented reality system accessible via the PokeCom. Robotic;Notes follows the story of Kaito as he discovers a peculiar report in Airi's database, one that would have disastrous consequences in the future.

In the wake of a third world war which left Japan in ruins, an organization known as Vischio seized control of Tokyo and renamed it Toshima. Taking place in its back alleys are battle games known as Igura, overseen by the Vischio, in which contestants battle and bathe in each other's blood to earn the chance to go up against its tournament's king, Il-re. Igura is not the only fighting tournament around; Bl@ster is a similar yet vastly different game since it prohibits murder and the use of weapons. The only way to win is by knocking out the opponent. Akira, a young man isolated from his family, is known to be undefeatable at Bl@ster. However, his life on the top is shattered when he is accused of murder. Unable to prove his own innocence, all hope is seemingly lost... that is until a mysterious woman named Emma appears and offers him a chance. Now, to regain his freedom, Akira must participate in Igura and ultimately defeat Il-re.

In the magical academic city of Ashram, girls known as Pentagrams study general education, magic, and etiquette to become proper ladies. Hidden from the rest of the world, the school is like a secret garden that is home to blossoming flowers. However, bugs sensitive to magic may target and trample them; as one of their tasks, the girls must exterminate these insects. The smileless Pentagram Arsnotoria lives in the fifth dorm house alongside her adored roommates: the cheerful Mell, the self-paced Little Alberta, the confident Picatrix, and the cool Abramelin. No matter what time of day, they hang out together as much as possible, and even throw tea parties in their secret room after completing their duties. The girls live in peace as they work toward their goal—but there may be more to Ashram and the Pentagrams beyond the calm life they have come to cherish.
