In the year 2020, a nation faces the pervasive threat of the Others—mysterious monsters who fall from the sky and feed on human brains. At the same time, psionics, a hormone that gives certain people extrasensory abilities that are effective against the Others, is discovered in the human body. Subsequently, the nation's founder establishes the Other Suppression Force (OSF) to combat these monsters and save humanity. Commonly referred to as the Scarlet Guardians, young individuals with psionics undergo intensive training to join this group. One day, the nation prepares an induction ceremony for the exceptional recruits who completed the grueling training to become Scarlet Guardians. Among these young elites is Yuito Sumeragi, the determined son of the nation's founder; at the age of five, he was rescued by a woman in the OSF. To repay this debt, he joins the organization, eager to put his training to good use. As he meets his new comrades, he faces a big problem—the woman who saved him years ago closely resembles one of his teammates. However, this should be the least of his worries—unbeknownst to him, a conspiracy is brewing, one with the capability to shake the entire country.

We still have no idea what's really going on with this show, beyond the fact that the weirdness is piling up! Curry-fiend Karasama remains oblivious to Tenma's crush, and Harima still hasn't confessed his true feelings to Tenma. But hey, the thug's got an excuse since he's caught up with his comic career and knee-deep in a blizzard of deadlines! Meanwhile, the love triangles are ever-shifting thanks to wannabe cupids and runaway brides. Even when you throw in a bit of cyborg love, a shipwreck, and a fugitive red panda–seriously, that ain't even scratching the surface. You are encouraged to scratch the pig, though. He likes it! And something rumbles in the next to last episode, no matter what I say next. School Rumble–The absolutely funniest show you’ll ever see that's not about anything that rumbles... Ever!

High school student Makoto Itou first notices Kotonoha Katsura at the start of his second semester, freshman year. Immediately, he becomes entranced by her beauty, but his bashfulness doesn't allow him to approach her, even though they ride the same train every day. Instead, he snaps a photo of her in secret and sets it as his cell phone's wallpaper: a charm that, if kept under wraps, would supposedly help you realize your love. However, classmate Sekai Saionji spots the picture, but instead of ratting him out, she offers to help set him up with Kotonoha—going so far as befriending her just for him. Thus, the trio begins a rather impromptu friendship. School Days follows the lives of these three teenagers as they traverse the joys and hardships that come with being a high schooler. In a story alive and brimming with romance and melancholy, the tale of these three students will linger in memory long after the momentous conclusion.
