The girl, Tokiko, is actually an alchemic warrior with a Busou Renkin, name of Valkerie Skirt, with the mission to exterminate Homunculi. She implants the only other successful work of alchemy than the Homunculus, the Kakugane, to take the place of Kazuki’s heart. The Kakugane resonates with his fighting spirit and forms a Busou Renkin (in his case a spear) so he can fight the Homunculus monsters who prey on humans. Kazuki joins with Tokiko to battle with the Homunculi and protect his friends and his sister Mahiro

Natori Touko, a third-year middle school student in the Eastern Private Defense Academy, is entrenched in field training with instructor Kamiya. It has been a harsh training regiment, but it is finally the last day. Kamiya proposes a extracurricular class under the name Newest Weapons Research. But then, an incident occurs that rocks all of Japan.

The story begins when high school student Kazuki Muto is killed one night saving a mysterious girl from a monster, only to wake up in his school dorm, believing it to have been a dream. However, he soon finds out that dream wasn't a dream at all when a giant serpentine monster attacks him and his sister. Tokiko Tsumura, the girl he saved, explains that the monster is a homunculus. Kazuki had been attacked and killed by it when he was rescuing her. However, she, feeling responsible for him, revived him by placing a Kakugane medallion in his chest, serving as a replacement heart. The Kakugane, as Tokiko explains, is an alchemical device that, when activated, takes a certain form based on the Kakugane's user, forming a unique Buso Renkin. The Buso Renkin is the only thing that can destroy a homunculus monster. Using this, Kazuki creates his own Buso Renkin (the "Sunlight Heart", a huge lance). Along with Tokiko and her own Buso Renkin (the "Valkyrie Skirt", an execution scythe), Kazuki joins the fight against the homunculi and their master.

High school freshman Rihito, who just came back from abroad, started a new life in Japan with his four Busou Shinki, female action figures with weapons.

The story will follow the coming of age and Shinki battles of Tsubasa, a boy who dreams of becoming a Shinki Master, and his Shinki partner Arnval Mk. 2.

The Private Aichi Symbiosis Academy was originally a high school for high-class girls. When it became co-ed, the girls, out of fear, asked to be permitted to bring weapons to school. When that was enforced, a five-member vigilante corps-like organization called the "Supreme Five Swords" was also formed. After many generations, the five swords eventually became a group which corrected problematic students, and the academy started proactively accepting such students in order to correct them. Nomura Fudou was sent to this school after being part of a huge brawl. What will he do when the only options he has after enrolling are being expelled from that school or being corrected the way the rest of the male students there were...by being forced to dress and act like a girl!

The anime centers on two protagonists. Koma Jinguji (Jay) is the smart and handsome student council president. His elegant smile captures the hearts of women. Tsubasa Hayakawa is a multi-talented and gentle shop assistant at a café. His cafe latte with owl latte art is very popular with female customers. The two men travel through time to fight their archenemy. The charming "Butlers," as they are called, fight supernatural battles and also experience a slapstick comedic life at their academy.

Our heroine Mari is an innocent, boy-shy, devoutly Christian young girl who's just entered a religious high school. When her best friend is kidnapped by a mysterious cult, Mari prays to the Virgin Mary for help. Instead, the Buddha shows up and tells her that she's going to be a magical girl. But not just any magical girl, mind you...none of this fuku-wearing, pink-wand-waving crap. She is presented with a sumo-style loincloth (magical, of course) and instructed to go kick bad guy butt. Being a good little Christian girl, the Buddha has to talk Mari into it, but she grudgingly agrees to bare her ass for the sake of her friend. And so Butt Attack Punisher Girl Gotaman was born! Villains beware her mighty ass of justice! Wedgies only make her stronger! Not even Darth Veda sumo can withstand her mighty posterior!
