Talk about being at the wrong place at the wrong time! High school student Kazuki Muto had no clue what he was in for when he rescued damsel in distress Tokiko from a monster known as a "homunculus." Disguised as humans--who actually eat humans--homunculi are malevolent creatures that affix themselves to people's brains, and once fully grown, the only thing that can annihilate them is a weapon called Buso Renkin! Follow the adventures of Kazuki after he discovers that it was actually Tokiko who saved his life by implanting a kakugane--an alchemical device that transforms into a buso renkin--to replace his heart! -- VIZ Media

Each year, the elite Hope's Peak Academy selects only the most gifted and talented students to enroll...plus one ordinary student, chosen by lottery. Makoto Naegi was that lucky person--or so he thought! When he shows up for class, he finds the elite students are a bizarre cast of oddballs under the ruthless authority of a robot teddy bear principal, Monokuma. The bear lays down the school rules: the only way out of Hope's Peak is to not only murder another student...but get away with it, as every murder is followed by a tribunal where the surviving students cross-examine each other! Inspired by the Danganronpa videogame series and based on the anime of the same name, the Danganropa manga is a quirky, fun, weird, and dynamic take on the high school Battle Royale genre.

Unlucky at love and with nothing going his way, Ota's world is turned over when he's magically transported into a land that time forgot.

High school students heroic act turns into epic human vs. monster sword fight! Buso Renkin is the story of teenager Kazuki Muto, who dies trying to save a girl who was being attacked by an eerie monster. The next morning, however, Kazuki is left wondering whether it was all a dream. Lo and behold, the girl, the monster, and his death are all real! The girl, Tokiko Tsumura, was actually trying to slay the homunculus (a beast that can take the form of humans, and whose main source of food is people), but Kazuki got in her way. To revive Kazuki, Tokiko replaces his heart with a "kakugane," an alchemic device that allows him to summon a lance with which to fight the monsters. It turns out that Tokiko is a member of the Alchemist Warriors, an organization sworn to protect the world from the diabolical creatures. Soon, Kazuki joins Tokiko in her quest to terminate the sinister being that creates and controls the homunculus. Kazuki inadvertently reveals his identity as an Alchemist Warrior to the Hayasaka twins, members of the L.X.E. (League of Extraordinary Elects), when he activates his Buso Renkin in front of them. After Tokiko and Kazuki take on the twins in a late-night battle, they learn the location of the L.X.E. headquarters, and head there along with Captain Bravo. Intending to put an end to Dr. Butterfly's organization, they discover that yet another evil plan has been set in motion...
