Shion || The mimic

she rests in her hospital gown during the final scene, Shion's long, dark brown hair is taken completely out of its signature high ponytail, allowing her straight locks to fall loosely around her shoulders while her neat, blunt-cut front bangs and framing side pieces still brush against her collarbones.

Shion is depicted to be caring and protective of her companions, demonstrated through her attempting to save Mika when she is captured by Akari and tending to an injured Hideo at the school. She also displays bravery, willing to risk her own life just to save her loved ones. She also seems to be sympathetic towards Yōkai like Akari herself, whom she refers to as a "poor soul" that she will put to rest in a dialogue of hers in Rage's Book: Chapter I. Shion appears along with her IJO companions, Hideo and Mika, in the back of a military convoy having a short conversation about their mission regarding clearing out the town and reporting any casualties before all three of them arrive at their destination, the convoy coming to a stop. They make their way to the neighborhood infested with the Gatas, who killed the residents.

They briefly clear out some of the Gatas together before Hideo goes on to tell them through the radio that they'll be splitting up and to meet back at the entrance of the high school at six. As the trio splits up, Shion fights her way through the Gatas and reports casualties whenever she can. At some point, when she heads near the outskirts of the playground, Shion encounters a mysterious Nekomata named Tama who then disappears as quickly as she saw it. Confused, she radios her companions, asking if they had seen the same thing. The two brush her off, thinking she is pranking them, and claims they haven't and that it must've been the fog. After that, Shion returns to doing her duty until all the Gatas were cleared out. Suddenly, she hears the screams of Mika through her radio. Panicked, she runs to the middle of the playground to find an unfamiliar monster, Akari Mizuno, who had captured Mika. Mika desperately pleads for Shion to help free her from Akari's grasp, shooting at Akari who is not at all deterred, but Shion, also shooting, could only watch helplessly as the Yōkai then kills her by devouring her head.

After watching her fellow comrade die in front of her eyes, in distress, Shion radios Hideo, with her vision blurring as she did so. Met with no response, she concludes that he must be at the high school and immediately runs there to only find Hideo, sitting back against a wall, with his right leg badly wounded. The two of them talk to one another. Shion silently informed Hideo that Mika was no longer with them before she goes to look for some bolt cutters in the back of a delivery truck (where a stalking Akari can be seen behind some boxes before disappearing) to use to cut the chains locking the high school's entrance gates. As she makes her way back, however, she encounters some more Gatas, and wonders if that unidentified yokai was the one leading them. She and Hideo then proceed inside of the school after Shion cuts the chains.

In the school, Shion tells Hideo to stay put at the first floor as they hold out here for back up and goes to search for some medical supplies. She finds a bandage in the nurse's office on the third floor before returning and using it on Hideo, the two of them briefly conversing and agreeing to discover more about the unknown Yōkai they encountered that could resist IJO bullets. As she and Hideo venture their way through the school, they find it littered with students now mutated into Gatas, as well as a rock containing a note thrown through a window from outside and some bullying notes about Akari Mizuno. They go to a classroom and open a locker containing a diary detailing Akari's backstory. After Shion reads it, however, she encounters Akari face-to-face, who nearly kills her. Hideo interferes, tackling Akari from the side, and telling Shion to run before being taken away by Akari as Shion watches on helplessly. As the lights throughout the school shut off, Akari begins to hunt her down. Shion finds clues leading to Akari's source of power in the form of "spiders" and shoots them one by one down, eventually stunning her. Shion then escapes from the school afterward.

Back in the neighborhood, Shion comes across Tama, again, who leads her to a forest. She is soon radioed by Hideo who tells her that he is patched up in a security room, but soon after, loses contact as her radio dies. Relieved to hear Hideo is still alive, she proceeds to the Inunaki Tunnel, recalling that there was an old IJO outpost located around here that could contact the organization. Unfortunately, though, it is sealed off. As she is checking the tunnel out, Shion encounters Akari Mizuno once again, forcing her to keep hiding in holes whilst reconnecting power to the outpost via transmitters. Once this is done, she makes her way to the sealed tunnel entrance to where Akari corners Shion and nearly devours her but is somehow saved by Tama at the last second, who uses its Shiroi Hono to put an end to the yokai. Tama then burns away the seal leading the secret IJO facility, allowing Shion to enter.

In the Inunaki Tunnel, Shion proceeds through as she sees the corpses of the IJO agents. She grabs an ID card from one of their bodies, gaining entry in the facility, and finds the place abandoned and littered with corpses of the lab agents and Muki matter. Shion goes to a computer to find it not responding. Realizing she needs clearance to the Director's Office, she grabs a clearance card from a dead lab agent (presumably the Director) and gains access. After putting in the password found on the Director's desk, she watches a recording of IJO agents making their way to the seal of Netamo, encountering some enhanced Gata classes on the way. When they reach his seal, they plant some C4 bombs in an effort to destroy him, however, this only led to awakening Netamo instead. He lets out a roar before the IJO agents cry out in pain and agony, with tentacles coming out of their bodies, fusing them into Muki.

Finishing the recording, Shion spots the same Muki as viewed in the footage, who suddenly disappears without a trace down the hallway. This results in the system lockdown of the facility triggering. She tries to leave before the facility closes her in, but the entrance is blocked off by debris and is suddenly jumped at by the monster. Shion escapes from the Muki's grasp after shooting at it and begins to repair valve and control systems in an effort to contain the threat after realizing she will not be able to fight it alone. After both the valve and control systems are fixed, she lures the monster into the containment chamber and locks it down.

Shion then proceeds to the stairs, however, the Muki manages to break free from the chamber and starts to chase her down the stairs to Sector E-7. Forced to shoot her way through the barriers and the Muki itself. While this is happening Hideo contacts Shion, who tells her that he had managed to get signal and that back up is on the way. When Shion soon reaches the first floor, the Muki abruptly falls from above and into the water, the body remaining still and most likely dead.

After a few moments, though, something rises from the Muki's remains. It is a Shiki monster known as Baigai, who encounters and speaks to Shion, and begins to roam Sector E-7 to kill her. To prevent this, Shion cuts the wires from several fuse boxes and turns on the power to shock the flooded waters with electricity to kill the monster. Baigai is electrocuted but tries to drag Shion into the waters with it. Shion, struggling to break free, reaches out to Tama, who appears in the corner of her eye, for help. Tama obliges, leaping towards her and ultimately helps Shion defeat Baigai as she pries him off of her and shoves him back into the water. Shion, shortly after, then passes out from the struggle after catching her breath.

She awakens at a hospital in her bed with a seemingly alive and well — user at her side, who tells her that she was found barely breathing by the IJO agents in Sector E-7.
