Kasumi Akai-Amsel/Plot

## Cerberus High II

### The Beginning

Kasumi makes her first appearance when she comes out of her classroom with Ascelin waiting outside in the hallway for her. He asks why she is such high spirits in which she replies by saying that she wanted to introduce him to someone. Nagisa emerges from the crowded hallway and it was hate at first sight for Ascelin. Nagisa introduces himself and explains how he was saved by Kasumi when she stopped a couple of jocks from bullying him. In truth they only fled because they recognized Kasumi as being Ascelin’s cousin and didn't want to face his wrath. Nagisa is grateful for Kasumi’s kindness and believes that he is in debt to her. Kasumi tells him that he doesn’t own her anything but Nagisa just couldn’t live with himself if he didn’t repay the one who saved his life. Kasumi thought about it and Ascelin hoped that she would tell Nagisa to hit the highway but Kasumi instead says that he can become the third member of her and Ascelin’s squad. Ascelin was vehemently against the idea but his iron resolve cracked easily with Kasumi's begging and puppy dog eyes. Ascelin announces that the three of them will be called the Arsy-Varsy Nectar Kiss.

Later in Kasumi’s solitary dorm, Kasumi thinks back on today with a smile. She grabs her precious feather from under her pillow and wishes to have a dream showing a good future with her squad. Just then Kasumi hears Miu’s cries for the first time but before she can question it, she falls asleep.

### Laika's Disappearance

The three of them meet up outside the school after Nagisa offers to take Kasumi and Ascelin to a pizza pallor. A sudden pain in the human's heart causes him to clutch his chest, alarming the cousin. Nagisa quickly recovers from this, revealing that he’s lost his wallet. Ascelin was just about to flip out on the sickly human before Laika suddenly appears with her squad Star Force. She tells them that whatever they're planning to buy, she can pay for it as long as they let her squad come along. After the two squads finish their pizza slices, they wondered where else to spend their money. Laika and Ascelin go to a clothing store while Laelaps and Teumessia went to an anime merch store. Finally alone together, Nagisa gets serious as he asks Kasumi if Ascelin hates him. Kasumi chuckles and tells her that he doesn't and explains how her cousin has always been overprotective of her. With a smile, Kasumi promises that Ascelin would warm up to him and to give him some time to.

When the two squads were getting ready to part ways, Laika suddenly gets a call that her father had passed and runs off in tears without telling anyone why. Kasumi learns of Laika’s disappearance the next day in class.

### Nagisa's Death

Kasumi is lured out of the headmaster's office into the secluded hallway of the school chasing after her precious feather. She encounters Miu in her corrupted state and instantly recognizes her as the one that was crying out to her that night. The dark influence on Miu is lifted a split second which Kasumi notices causing the black vixen to conclude that she had been brainwashed. The darkness regains its controls over Miu and she powers up an shadow attack when suddenly, Nagisa appears and sacrifices himself in order to save Kasumi.

Nagisa isn't instantly killed by this attack, contrary to Red Star's prophecy, and he uses this opportunity to warn Kasumi. However, Nagisa bites off his tongue and dies before he is able to utter the vampiress's name. Ascelin arrives at the scene with his wrist blasters blazing but Corrupted Miu retreats before any of it could hit her. Nagisa’s body is taken to the infirmary where Kasumi grieves. As the rest were trying to make sense of the strange circumstances of the human's death, they were hit by the horrible smell of Nagisa's body decomposing.. As Kasumi was being dragged out by Ember kicking and screaming, Nagisa’s body completely deteriorated under his sheet.

### The End

Kasumi is beckoned once more towards Miu's presence and is relieved to see that the dark-skinned female is no longer under mind control. Miu fearfully tells her to stay back as she may have regained control of her mine but her body its still acting on its own. Despite this, Kasumi is still hellbent on saving her and tries to convince the others to not attack her when they arrive. Miu begs for her own death as that is the only way she can be freed from this hell and explains why she was chosen to wield the Sword of Supernatural Calamity. Since Miu is the two gods’ ‘fur and feathers’, her wielding the sword would be bond to split the earth in two with just a single slash into the air. And it wouldn't be just their earth, the many other earths throughout the vast worlds in multiverse would be met with the same horrible fate.

Red Star flies up to them in her original star form and slots herself inside the sword, becoming the final piece. From within the sword, Red Star begins taunting Kasumi and reveals the truth about Nagisa’s existence including the fact that he never loved her. Kasumi is shocked by this revelation and Red Star uses her despair to convince her to abandon her efforts on saving the world. Miu cries out as she raises the sword but doesn't get to bring it down because Kasumi transforms into Shadow Kasumi. The black flames from Shadow Kasumi’s transformation blew the other characters away and knocked the sword out of her Miu’s hands. Laelaps catches the sword and Blanc freezes the sword so it is completely harmless. With the Sword of Supernatural Calamity out of her hands and her body back under her own control, Miu fearlessly tries to get Kasumi back to her senses but the black vixen’s rage is unstoppable now as Shadow Kasumi. Shadow Kasumi grabs Miu by the throat and a lightning photosphere engulfs both of them.

Kasumi wakes up to find herself swimming in a black sea and sees Miu sleeping while tears flowed out of her eyes. Kasumi attempts to wake her up by apologizing to her for letting her despair overcome her before beginning to cry herself. It is when she hears the voice of all her fellow students that had disappeared telling her not to give up. Kasumi wipes away her tears and once again gets Miu out of her slumber by telling her to listen to all the voices and how strong they sound.

Miu finally opens her eyes and awakens in her strongest form, not because of the reignited love of Shun and Inugami but because the need to protect the earth which is the everlasting product of the gods’ short-lived earth along with the many others that exist. In Seraph Miu’s arms is an unconscious Kasumi who had been rid of all her hate completely. Suddenly the sword encased in ice starts levitating into the air and shatters revealing Red Star in black armor made from the essence of all the cryptic canid breeds. Red Star flies towards the two and Seraph Miu teleports Kasumi away so that she is in the arms of both of her dads below.

Red Star's defeat causes all the students and staff to be freed from the Sea of Darkness. When Seraph Miu is asked what she is going to do now she only smiles as the ghost of Nagisa appears. He reveals to Kasumi that his feelings for her were true. Kasumi doesn't know how to feel about this but Nagisa embraces Kasumi and the black vixen melts in it. Seraph Miu summons a flute and tells everyone that this song that she is about to play is one that the joined hearts of the two gods would sing. Everyone slow dances to the music until it is time for Nagisa and Seraph Miu to depart from this world.

### Epilogue

The epilogue takes place 6 months later when Xiomara finally gives birth. It's a baby girl and while thinking up a name Kasumi suggests one that has a similar meaning to Miu. As he was holding his sister, Ascelin suggests Lumaia since it has the same beautiful meaning as a feather.
