It's not easy being good at everything. First-year high school student Natsuo Ishido has always been a gifted athlete, and her ability to easily master every sport has not only bought her a life of boredom, but the resentment of everyone else who has had to work hard for their achievements. Not that Natsuo cares what anyone else thinks. All she longs for is a break from the monotony...for a real challenge worthy of pouring all her efforts into. A rival-an equal-worth beating down, crushing...

After her first amateur fight ends in a swift KO, Natsuo is disappointed…not in her dominant performance, but because the win came too easy, a far cry from the brutal challenge that she craves. When she finds out that her rival Yuzuko Mawatari will be entering the rookie selection competition for the big G-Girl tournament at the end of the year, it lights a fire under her. She trains single-mindedly for the chance to pummel Yuzuko's little face in the ring, but her coach thinks it's far to...

Natsuo reveals her true colors when she humiliates one-time rival Haruka Kirido at an amateur grappling competition. Unable to deny her monstrous talent any longer, Karin reluctantly allows Natsuo's entry into the G-Girl Rookie Selection Tournament, where she hopes to finally lay her gloves on that hateful Yuzuko Mawatari. After a month of hard training, the only hurdles that remain between her and Yuzuko on tournament day are the elite competitors in her bracket. Among them, a wrestling s...

Natsuo joins the Takenaka Dojo, where she starts training under pro MMA fighter Karin Kontani. Each day is a tough grind-endless training exercises, grueling grappling sessions, getting “volunteered” to be Karin's demonstration dummy for her class on takedowns, and having her butt handed to her by snarky fellow first-year Haruka Kirido's jiu-jitsu…but for once, she isn't bored. When the team goes to support a dojo member competing in an amateur grappling tournament, they're shocked to see ...

Having secured her place in the final round of the tournament, Natsuo's goal of pummeling Yuzuko's insufferable little face is finally within reach. Relieved and exhausted, she falls asleep in the locker room…but as the cage door closes on the remaining semifinal match, Yuzuko's place in the final match is far from assured. Unbeknownst to Yuzuko, her opponent has an ace up her sleeve-a unique attribute and a skillset tailor-made to defeat her.

After all her hard work and hard-fought wins, Natsuo finally stands across the cage from the girl who has vexed her from the start-intolerable, unacceptable Yuzuko Mawatari. Fresh off of dispatching Doona Park in monstrous and off-puttingly cheerful fashion, she beams at Natsuo from the opposite corner, just as excited for the chance to finally meet in the ring. It's time for these girls to have a conversation.

After being completely overwhelmed by Yuzuko Mawatari's jiu-jitsu in a rooftop sparring session, Natsuo resolves to learn the mixed martial arts skills she needs to take her down. She officially quits the volleyball team, and starts looking for an MMA gym to join. When she's waylaid by an irate Captain Sawamura looking to get even for Natsuo crashing the karate club and defeating her lieutenant, it's the perfect opportunity to try out what she's learned…

After knocking out her first opponent with a perfectly-timed knee, Natsuo comes face-to-face with Sanae Sawamura in the next round of the tournament. Icily determined to serve Natsuo some long-overdue payback, Sanae proceeds to outclass her with her superior striking skills. As the fight starts to slip away from her, Natsuo finds herself reminiscing about a time, long ago, when she and Sanae had been close…a time when so much in Natsuo's world had been very, very different.

The fateful day has arrived-with their preparations finally complete, Assistant Inspector Hirama's government task force springs into action, encircling city hall to capture Mayor Hirokawa and the parasytes within. At the same time, Ebisawa's fanatical followers fan out across the city to unleash their doomsday terrorist plot, while an unsuspecting Tatsuki and Detective Fukami hurtle toward their final confrontation with Ebisawa himself. As the conflict between humans and parasytes explode...

Three dismembered bodies were found in an abandoned basement parking garage, sliced limb from limb while they were still alive…and if the boy who discovered them is to be believed, the murders occurred in an impossibly short window of time. Nothing is adding up for veteran detective Fukami of the East Fukuyama police department, and his gut is telling him the boy is hiding something. In fact, he's quite certain that Tatsuki Hirokawa saw exactly what happened, and who did it. But what the b...

Ebisawa is back in town. But when the killer cult leader shows up at his door, Tatsuki misses his chance to stop him. Meanwhile, Assistant Inspector Hirama slowly closes the noose around Tatsuki's father and the parasytes at city hall. Caught between his familial loyalty and the police, Tatsuki will soon need to decide where exactly he stands. All while Ebisawa and his followers remain at large, advancing their mysterious doomsday plans…

Some months have passed since the killer's attack, and the trail has gone cold. Back in school, Tatsuki obsessively pours his time into the archery club. His physical wounds may have healed, but his grief and anger have only continued to burn out of control. The police believe the killer left town long ago, and are doubtful he'll ever risk returning. But as the heat gradually dies down, Tatsuki feels a growing conviction in his bones: the killer will come back-soon-and when he does, he's g...
