Warning: Spoilers Ahead!
The fourth episode of ID: Invaded starts off with a familiar face being interrogated by the Kura team. Tensions are already high, and Fukuda keeps the team on their toes after he displays his superior intelligence. He comes to the conclusion that Kura is using a killer to snuff out other serial killers, and points out how each time Narihisago returns from and ID well, he adds a new layer of despair to himself. It’s no surprise that Fukuda figures the team out, but the interesting moment of the first part of the episode is the decision of implanting Fukuda into the Mizuhanome instead of Narihisago, since he is in solitary confinement. After the multiple deaths of Anaido, Fukuda’s ID well persona, Kura determines that the serial killer is not up to the task, and Fukuda even jokes about how someone who has tried to take their life in the real world has a low survival rate in the ID well. Serial killers, you can’t use them or get disposed of them, am I right?
The scene then cuts to a young girl waking up, to only find herself caught by the Gravedigger, and encapsulated in a barrel. She is left with a small canister of oxygen to prolong her suffocation, and her whole experience is being live streamed to the world. No one seems to really be panicking over the girl’s abduction, since this is the Gravediggers sixth victim, and at this point it almost seems like a norm for them. Luckily the Kura team is hard at work, but for some reason the past victims were never saved because there were never any cognition particles left behind, until the recent abduction of Keiko Kikuchi.
The Kura team has been in a hiatus because of Narihisago’s confinement, but after uncovering the new cognition particles, Sakaido is called back to action. The brilliant detective is transported to a world of burning buildings and charred bodies. After noticing Kaeru’s burnt body, Sakaido notices a small girl on the highest level of a burning building. Sakaido tries to navigate the complex realm, but continuously dies over and over again. Normally, when a person enters the ID well, they have no recollection of past experiences, but Sakaido is somehow able to get past the obstacles that stopped him in prior explorations, allowing him to advance a little more each time.
What one forgets to realize is that Kura is entirely devoted to finding the victims that are being targeted, especially when the Chief Hayaseara tells the team to get some rest after searching nonstop for two days straight. It is also announced that Narihisago is constantly exploring ID wells for six hours at a time, with brief moments of rest. Since results have not been advancing, the Chief grows weary of the team, and questions Narihisago’s desire to save people. Maybe internally, he doesn’t really care about saving people, but would rather learn about a person’s deepest secretes to expose their weaknesses to drive them to suicide later on. Kazuo begins to have doubts, but of the killer, not Narihisago. He begins to question why out of all the victims, only this abduction had cognition particles laying around at the crime scene. That is when he deduces that maybe there is a copycat, and the ID well belongs to a different killer.
Well, if you had your doubts, Sakaido flips the tables yet again. The music changes to an upbeat rhythm as Sakaido is navigating the ID well like a champ. He begins to overcome obstacle after obstacle, and even gets cheers from the Kura team as they watch eagerly from headquarters. Sakaido is able to reach the highest floor with the persona of Kikuchi, and uncovers that the false Gravedigger is Mr. Oono. After uncovering the culprit in real life, Mr. Matsuoka and Hondomachi arrive at the scene with back up and apprehend Mr. Oono. As the team rushes to the rescue of Kikuchi, the live stream is still showing her fighting for her life, but once they open the barrel she’s in, they uncover a rotten corpse. The live stream was actually a pre-recorded video, and Kikuchi had been dead for days.
The episode comes to it’s bizarre conclusion with Narihisago and Momoki having a brief discussion. Momoki lets him know that the killer was apprehended, but the girl was not saved. Narihisago can’t help but remember the innocent little girl he saved form the ID well, and is asked if he would like to kill the false Gravedigger. Narihisago tells Momoki that he doesn’t particularly have any resentment towards the killers he’s helped capture. He instead develops an overwhelming urge to kill someone because he realizes that he can drive them to suicide without fail. After questioning his humanity, Momoki asks Narihisago if they are still friends; evidently, they still are. The final scenes are of Hondomachi discovering a familiar face in the crowd of overseers. She tries to corner the mysterious man, but is confronted instead, and is left off with the man giving her a kiss on the lips; romance is in the air.
ID: Invaded continues to lead the viewer in the maze of mysteries that seem to have no end for the series. Diving into the relationship between Narihisago and Momoki begins to paint a clearer picture as to why Sakaido has been the primary pilot of the Mizuhanome. Narihisago’s motives are also a bit unclear, but overall his intentions are pure, and they are clearly displayed when he takes on the persona of Sakaido.
The true intentions of Narihisago are still muddled, but through his actions, he overcomes his internal struggle; justifying his humanity.
