With Lisa's help, the shinobi succeeded in releasing him, however they are too late to stop Donovan from beginning Phase 4 of Project Alpha: The noise leads one of the scientists, Lisa Hamilton to them and Kasumi demands to know where Hayate was. Kasumi only managed to escape from the village alive thanks to Christie and good timing.
The next day, Kasumi thanked Hayate and Ayane for their help before taking her leave, swearing to defeat Donovan at all costs. As she tries to convince him to stop the war against DOATEC, Hayate remains quiet and Ayane arrives to interrupt them, providing enough of a distraction for Hayate to leave and continue on with his mission.
Major plot details and endings below. Their battle ends in a Torn Sky Blast duel, and with the help of Ryu Hayabusa from the sidelines, Kasumi overpowers Raidou in the end and he is finally killed.
She manages to defeat Raidou, and was happy because she thinks she had avenged Hayate, but Raidou awakens stronger than before, with inhuman strength caused by DOATEC experiments. She wonders why it always leads her again to the island.
Worried about everyone's safety, Kasumi risks her life visiting the outside of the village, and finds Hayate. Hayabusa sent a message to the real Kasumi telling her of their problem and she finally comes out of hiding to aid them.
Although Kasumi didn't know Christie, she jumped on the helicopter and they flew away from Ayane.
Lisa tries to silence her by threatening to shoot her, but Kasumi is saved by Hayabusa, who takes her after from the building, after Lisa and Alpha escaped. After the fight, Kasumi escapes again and goes into hiding once more.
However, once Ayane learned of her true heritage, as a young adult and she now knew that they were half siblings and cousins, Kasumi's friendship with Ayane ended due to her bitterness and envy over her mistreatment by the clan, centering her animosity on the "princess" Kasumi. Ayane tried to stop her on the bridge just out of the village, but Kasumi was saved when Christie appeared on a helicopter and separated the two shinobi with gunfire.
When she sees Ayane, she panics and runs away again. From a childhood, Kasumi has been pampered and spoiled as she lived a privileged life full of expensive clothes, servants and the respect of the rest of the Mugen Tenshin clan.
Following a long battle against Alpha, the clone and the lab is destroyed, with the shinobi managing to escape. After much travelling, the clone got fed up and returned to Helena demanding for Alpha's location.
She appears to have become ill from running and living rough, because she develops a fever. After the match, having herself escaped the burning building, Kasumi is last seen watching Helena entering the blazing helipad.
Edit Homesick and constantly hunted, Kasumi still wishes to see Hayate, but has to go into hiding from the Mugen Tenshin clan again.
She rushes to the oil platform and fights her way past Christie and Rig to get to Hayate, who had been forced into reactivating Project Epsilon. As Kasumi tries to stop her, Ayane prevents her from going after Helena, who by doing so saves Kasumi's life as the building starts exploding mere seconds later.
Wanting to know the truth, Kasumi turned to Ayane, and believing that Kasumi will never become a great leader anyway, she tells her that Raidou was the fiend who harmed Hayate. She fights her clone to her best efforts but in the end it appears Alpha escapes in the chaos of the destruction wrought by the Mugen Tenshin invasion.
Kasumi fights her way through the tournament, and does come out as the winner of the tournament, meaning that she will have to face Raidou in the Danger Zone. Kasumi crosses paths with Ayane, but apparently her sister is focused on taking down Genra, so she isn't going to kill her; although Ayame has previously asked Ayane to help Kasumi rather then be against her. During the last day on nuove slot machine aams gratis island, she found out that maybe she had come to the island in order to remember her life before running away.
This clone believed that it was the real Kasumi and held the same desire to locate and destroy Alpha as the original did. She spends some time in the geisha district of Kyoto during her running, and to cover up her shinobi identity, she dresses as a normal high school girl and acts like a normal civilian in public to get by.
The clone felt that it needed to face Alpha by itself and left.
