I originally intended to write this post just to share my thoughts on the different adaptations of Teru Mikami. However, while I was thinking about how to discuss his appearance in Death Note: Light Up the New World, I decided that I would also go into detail about one of the worst ideas ever conceived in the Death Note franchise, one that I'm surprised people don't talk about more often. If you'd like, you can skip ahead to the paragraph beginning with "FINALLY" to get to the main point of this post.
I think it's safe to say that Mikami was one of the best things about the second half of the anime. His extreme sense of justice, his creepy and exaggerated facial expressions, his epic way of writing in the notebook, and so on, made him one of the most beloved characters in all of Death Note. I'm sure he even managed to rekindle some people's interest in the story after the tragic deaths of L and Soichiro.
The first thing I want to discuss is the differences between the anime's Mikami and the one featured in Death Note Relight. In the series, Mikami spends most of his screen time being portrayed as a stoic badass who acts as a ruthless crusader against evil. We even get a flashback to his tragic childhood, which allows us to empathize with him. However, once we reach episode 36, we finally get to see just how horribly disturbed he really is, as he writes down the names of the Task Force and FBI agents with a demonic unhinged expression on his face. I still remember how shocked I was the first time I saw such a cold and calculating character completely lose his mind. It's easily one of my favorite twists in the series.
However, the Relight movies portray Mikami differently. We get new scenes in which he mercilessly murders a television crew simply for criticizing Kira, as well as another scene where he talks to Ryuk about the role God has assigned him. In the latter, Mikami laughs like a maniac while spinning around in his office chair. From the very beginning, it's made abundantly clear that he's a complete nutcase who's even crazier than Light. Both anime versions of the character are quite interesting in their own ways.
Next, we have the 2015 J-drama. While this live-action adaptation is notorious for drastically changing the personalities of almost every character, Mikami is one of the characters who stays closest to his original counterpart, alongside Matsuda. The actor looks and behaves almost exactly like his manga counterpart while also adapting the character effectively to the live-action series' dynamics. I absolutely love how he recreates the iconic DELETE scenes without resorting to the anime's over-the-top exaggeration. Definitely one of the best casting choices in the series.
The storyline they gave Mikami in this adaptation also pleasantly surprised me. He's introduced in the first episode as the prosecutor who handled the case against the guy who murdered Misa's parents. The scene in which Mikami informs her that her parents' killer is being released from prison does an excellent job of showing just how disappointed he is with the justice system he works in.
After that, Mikami makes sporadic appearances throughout the first half of the show, watching the Kira phenomenon grow and receiving some information about L's investigation without directly interfering with the plot. The only notable exception is when he confronts an amnesiac Misa and demands that she reveal she is Kira.
It's in episode 8 when Mikami truly becomes a major character. He steals Misa's notebook and starts purging criminals on his own until Light contacts him and convinces him to form an alliance. After being the one to kill L, Mikami assumes the same role he had in the original story: eliminating criminals in Light's place to avoid raising suspicion.
Mikami is eventually caught alongside Light when they attempt to kill Near. However, Mikami gets off much more easily here than he does in the anime, as he simply starts a fire that accidentaly destroys his notebook, erasing in the process his memories as Kira. I was genuinely surprised that Mikami survived the live-action series. My personal theory is that he ended up in a psychiatric hospital. Feel free to share your own theories about what happened to him.
FINALLY, we come to the Mikami featured in Death Note: Light Up the New World, a sequel to the 2006 live-action movies that revolves around the successors of Kira and L facing off against each other.
Mikami could have played a fantastic role in this movie, serving as the new Kira and attempting to evade the Task Force. Instead, we got one of the worst plot twists in the entire Death Note franchise.
To put it briefly, the main villain of this movie is Yuki Shien, who obtains a new Death Note that originally belonged to Mikami. As it turns out, Mikami had been secretly taking care of Hikaru Yagami, Light's secret son, this entire time.
WHAT...THE...HELL?!
Okay, first of all, let's provide some context. Just like in the J-drama, Mikami was the prosecutor who handled the case against the man who murdered Misa's parents in this universe. For some reason, Light decided to entrust his son, Hikaru, to Mikami before his death.
Hikaru received a new Death Note that Ryuk dropped into the human world and began mercilessly killing people, which eventually led Mikami to kill him and take possession of the notebook. Mikami himself was then killed by Yuki shortly afterward.
For starters, WHEN DID LIGHT HAVE A SON? WHO DID HE HAVE A SON WITH? AND HOW THE HELL DID HE EVEN HAVE TIME TO HAVE A SON?!
Let's remember that this movie takes place in the continuity of the 2006 live-action movies, where Light loses to L just a few months after becoming Kira. There are no time skips, we know what Light does all the time, and Light NEVER gets sexually involved with anyone. He doesn't even sleep with Misa.
But even if he had, how could Light have "entrusted" Mikami with taking care of his son? If Misa had gotten pregnant, she wouldn't have found out until after Light's death, meaning Light couldn't possibly have entrusted his child to anyone beforehand.
I also find it incredibly strange that Light would trust Mikami so much, considering that Mikami doesn't even exist in the 2006 live-action movies, and we're never given any indication that the two of them have any kind of relationship.
And if all that weren't enough, both Light and Mikami feel completely out of character here
Light isn't the kind of person who would willingly pass his legacy on to someone else. He's an egomaniac who wants all the glory for himself. He wouldn't want his son to accomplish what he himself failed to achieve.
And Mikami, according to the movie's novelization, abused Hikaru before eventually killing him. You're telling me that someone like Mikami, who practically worships Kira, would abuse and murder the son of the very man he considers a god? Shouldn't he see Kira's son as some kind of messiah?
Seriously, I'm at a loss for words. It's bad enough that they came up with an idea that was terrible from the very beginning, but somehow they managed to execute it even worse.
And it doesn't help that the actor playing Mikami doesn't look anything like the character. Is it really that hard to cast someone who wears glasses and has slightly longer hair? Seriously, what an absolute mess they did with Mikami there
