When Ha Eun takes shelter from a sudden downpour, she runs into someone she recognizes as her classmate. She greets him but is met by a cold shoulder, his curt replies shutting down her other attempts at conversing with him. When the awning above Ha Eun tears apart, she takes cover under the boy's umbrella and accidentally hugs him. Abashed and still annoyed, Ha Eun apologizes as the boy boards his bus. As luck may have it, the two meet again when Ha Eun's university friend, Yeo Reum, invites both of them for dinner. The classmate is introduced as Yeon Woo and turns out to be Yeo Reum's childhood friend. After several drinks, another friend of Yeo Reum escorts him back home, leaving Ha Eun and Yeon Woo alone. The two share an intimate moment devoid of words. Will this be the first of many? [Written by MAL Rewrite]

In a world plagued by magical dangers and threats, there exist special warriors—known as Inquisitors—who are tasked with non-violently preventing these threats and nefarious actions. The Anti-Magic Academy is a specialized school built to educate and train these Inquisitors, which splits its students into small squads in order to train them to work together. Among these talented squads is the 35th Test Platoon, also known as the "Small Fry Platoon" due to its low ranking and incompetent members. However, everything changes when Ouka Ootori, a powerful yet rebellious former Inquisitor, is forced into joining due to her tendency to break rules and committing a serious violation: the killing of a witch. Tempers flare upon her arrival, as she clashes with their clumsy captain Takeru Kusanagi and argues with the rest of the squad over her views on witches. This eclectic group has a long way to go if they wish to succeed and climb the ranks at the Anti-Magic Academy: they must first set aside their differences and come to work together as a team.

Koushi Inuzuka is a smart high school student who aims to become a public prosecutor. Unfortunately for our good guy, he was born into a martial arts family whose head (ie his father) only knows one language: violence. When Koushi was still a baby, his father made a pact with his biggest rival to marry Koushi to his opponent-turned-friend's daughter. The union of the two blood lines is supposed to bring forth Earth's strongest martial arts clan. Skip forward: Koushi is in high school, oblivious to the marriage arranged for him at his birth. Enter Momoko Kuzuryuu: sugar bomb, airhead, loli martial arts artist and Koushi's self-proclaimed bride (the strongest on Earth, no less). Her wish for sexual intercourse meets with Koushi's square refusal as he has absolutely no desire to get it on with someone who looks like she could be his little sister, not to mention that he doesn't have the foggiest idea who she actually is. Meanwhile, a war has broken out between the martial arts families. For Koushi, this means that numerous fighters are out to challenge/assassinate him. As if that weren't bad enough, our protagonist also has a fight phobia due to a traumatic incident that took place in his childhood. Now it's up to Momoko and her superhuman fighting skills to protect her "husband." Will the two sweethearts survive the trials and tribulations ahead of them? More importantly, will Momoko get her way receiving a baby from Koushi? (Source: Kotonoha)

Crisis befalls the main characters and the Earth as well! How do they deal with the conspiracies that they have uncovered, while protecting the Earth too? (And what happens to the cliffhanger at the end of the previous episode?) In these final two episodes of Stratos 4 Advance are the exciting conclusion to the whole Stratos 4 series. The main characters will have to draw on all the resources they have, their friends and allies and their own sheer force of will, to "bring tomorrow to Earth," as one of the characters puts it.
