He is the younger twin brother to Yuika Ketōin and apart of the bloodline to the top underworld conglomerate - the Ketōin Conlgomerate. When the World Domination Proclamation began, both he and his sister involved themselves by aligning with Byakuya Togami, essentially becoming the first allies he acquires.

### Prior Life

*Main article: Hiroyuki Ketōin (KFS)*
Hiroyuki was born as apart of the bloodline to the top underworld conglomerate - the Ketōin Conglomerate. Alongside his older twin sister, Yuika, he would be raised under of such organization. As he grew up, he and his sister would have Taeko Kanai joining their conglomerate as a bodyguard of sorts - someone who openly had a crush on Yuika (though she didn't seem to register the advances) and who openly disliked Hiroyuki. However, Hiroyuki would become aware that she was a spy for the Hasegawa Research Institute.

### World Domination Proclamation

Prior to the Proclamation, the Ketōins and Taeko got wind of Byakuya being in Prague and travelled their to learn why he was there. Thus, However, with the World Domination Proclamation going underway, and upon seeing Byakuya Togami and Blue Ink surrounded by Sonia Nevermind's forces, Hiroyuki went to assisst them. As Taeko attacked the soldier with her guitar, Hiroyuki and Yuika picked up both Byakuya and Blue Ink in his Mercedes-Benz before driving off. Following introductions, he reveals that not only does he know the one doing the Proclamation is a fake Byakuya, he's also there mainly to get information concerning the Secret to the Togami Family's Prosperity. However, even after threatening to kick Byakuya out to the crowd (though its clear he isn't too serious about it), Byakuya refuses to spill any details and dumps the contents of a Pilsner Urquell all over Hiroyuki's head. The group drive was briefly interrupted by Sakura Ogami, who wanted to capture Byakuya for Hope's Peak Academy, but they manage to evade her after Hiroyuki and Yuika activate the car's jet boost function to overpower her and drive away.

They continue driving up until they reach an anti-Proclamation protest that gathered a large crowd. It was during this time that Hiroyuki hands over a satellite phone to Byakuya, while Yuika tried to give Byakuya some spare clothes (since his original clothing was stolen from him). She first presents a sailor fuku, before handing him a spare tuxedo. Taeko would soon arrive back to proudly declare she defeated Sonia's personnel and tries to climb back into the Mercedes only to find herself stuck due to her large breasts (which Hiroyuki comments on and mocks her for). Once Taeko saw Yuika's uniform, she became excited and mistakenly thought that if she could strip off her clothes she could get it instead. However, she was still stuck and the commotion brought from her attempt got the crowd's attention. Ultimately, the group was force to drive off and leave Taeko to get assaulted by the crowd.

As they continue to speed off, the car is chased by a mechanical flying baby that is equipped with a machine gun (modified by Kazuichi Soda and Sonia Nevermind in her tinted, armored car. Ultimately, while Hiroyuki is unable to use the boost function from before, they are able to escape as Byakuya tosses out the last article of clothing he had after being knocked out: his glasses that were equipped with a hidden tracking device. From there, Hiroyuki takes all four back to the twin's hideout at the Skoda Auto factory.

Once there, he ends up talkng with Blue Ink concerning her being able to accurately name German military, with her clarifying its because of her Borges a cyberntic eye that holds AI. When Hiroyuki grabs cigarettes and beer, Blue Ink scolds him since he's underage, but he brushes her off and teases her on the possiblity of her using Borges to look up lewd words or other activites, eventually resulting in Ink telling him to shut up. After handing off the satellite phone to Byakuya, he goes to take a shower to wash off the beer from earlier.

Later on, he joined the trip to the Church of Bones, asking about their purpose there. In turn, Hioryuki is given the information about Byakuya's membership to the Council of Global Controllers, though is skeptical that just one organizaiton can truly be enough to run such a chaotic world, and talk about the  Despair Novel. He would be present for when the fake Byakuya lured a crowd over to their location, who proceeded to set the place on fire. Yuika and Hiroyuki would witness this after climbing onto the church's steeples. Thus, Hiroyuki would also witness the threeway fight which comprised Sakura (who was now on Team Byakuya's side), Sonia and Kazuichi (who were piloting a robot that the latter built) and finally against the Hasegawa Research Institute. Comprised of The Chief, Subordinate Kanai and even Taeko (who he reveals actually works for the Institute, much to Ink's chagrin). Ultimately, the Institutes comes out on top against the Hope's Peak students before kidnapping Yuika and Byakuya. As for Hiroyuki and Ink, both would've died in the church's collpase if Hiroyuki didn't have his car drive remotely to their location (which gets him scolded for not using his car earlier to get them to safety).

They give chase using GPS, with Hiroyuki even putting on his parody song to help lighten the mood, though he assured Ink he was taking things seriously. His rambles were cut off by Junko Enoshima contacting them by satellite phone and giving a report on the findings she made back in Japan. Namely finding out there was an Ultimate Imposter who could be the one impersonating Byakuya. He would also heard the broadcasts from the Imposter that would signal them dropping a satellite somewhere in the Czech Republic and the Hope's Peak conference concerning the Proclamation. Eventually, try as they might, while their location was Detsky's Island, they couldn't find a bridge to cross due to the riots stopping all form of traffic. As the car faced the Vltava River, Hiroyuki goes on to express that while Hope's Peak only serves to churn out freak shows, he believes 'you know what' to hold real power and that he feels he can't ever be the star. Instead, he believes Blue Ink could be, though she expresses her belief in just being Byakuya's property. Hiroyuki compliments her and says she's more than cappable as the Ultimate Secretary and a good storyteller in her own right. He gives these as his parting words as he drives his car into the river, using an eject function to see Blue Ink shooting towards the island as the vehicle sinks into the water with him in it.

### Ordeal With Blue Ink

However, Hiroyuki survives this affair and is able to escape, acquiring a new car in order to catch up with his old ally. This affair leads him into the United Nations convoy that was just hit with an incendiary bomb and was on fire. Upon seeing Blue Ink with her brothers, Kazuya Togami and Suzuhiko Ōtsuki, he drives up to her when Kazuya is in utter terror from the fire and speeds off with her her. During this ride, given how much unreality Ink had been experiencing, she asks who Hiroyuki truly was, but he says that it doesn't really matter. They hide out at the Karlovy Vary, which had Hiroyuki briefly eager for some hot springs to enjoy, but becomes disappointed when Ink reveals its for joking (he also goes silent when she implies her interest in such affairs relates to her attraction to Byakuya).

Arriving at the hotel, both dine and refresh themselves, with Hiroyuki eating with Ink after she wakes up from a long rest. During this feast, Hiroyuki states that 'Hiroyuki Ketoin' is not his name nor does the Ketoin Conglomerate exist before asking her why she ever thought that. After she responds that she got it from Borges, Hiroyuki asks if its possible Borges is showing her a false worldview. Hiroyuki goes onto a spiel about the role of secretaries in the old eras. How they once stood at the pinnacle of society, but had to resort to eventually making up fiction in order to stay relevant. Something that gets Blue Ink to note he was well-read, which has him state he just like to read in the library when he was younger. He largely suggests Ink was overelying on Borges for her talent, and that it was just feeding her lies. He states that, unless its a prophecy, people should never rely on something 100% of the time, and it was good to be skeptical.

### Hiroyuki's Fate

When Ink asks again about who Hiroyuki was, he merely states that his identity isn't important and stuff like like Hasegawa Research Institute was just fiction that people shouldn't believe as being real. He encourages Ink to use her head nonstop, just like how she was during the Legacy Crown Championship. When Ink asks about him one more time, he finally reveals the truth: he was Blue Ink's longtime companion. But, if she forgot about even that, Borges must have eroded her past away. It was then that Hiroyuki would be shot in the forehead from a sniper, which would turn out to be Yuika. However, just before he collapses dead, he encourages Blue Ink to 'be herself' and slips hers a note that holds one letter: 'K'.

### K2K System & Speculated Identity

Ultimately, Hiroyuki Ketōin's appearance and personality was merely an obfuscation Borges made by overlaying the character from the Kagami Family Saga in real-time over someone else. It's unknown if the person who was thought to be Hiroyuki is actually related to Yuika. Despair High School was unable to find out the identities of who both were.

Given the reveal that Blue Ink and Orvin Elevator, were not the real Shinobu Togami and Kazuya Togami, that Ink was actually the Kudan, and how Hiroyuki notes that he was a 'companion' to Ink (a word that Kudan refers to those who have proved themselves to her), and enjoyed reading at the family library, its entirely possible that Hiroyuki may actually be the real Kazuya Togami, whom in the fabricated AI flashback version of the character had those characteristics. Some speculate that this also could mean that Hiroyuki is merely a projection of the AI of borges as well, which dies when her eye is shot, however this theory has some complications with other parts of the story. It could also be that he is simply entirely unrelated as well, that Blue Ink once knew.

## Skills & Abilities

### Driving Prowess

While he doesn't have a license, Hiroyuki is a skilled driver, capable of weaving throughout Prague with efficiency to avoid crowds or Team Byakuya's pursuers. He's also knowledgeable concerning the capabilities that his Mercedes-Benz hold and has the competence to use them at the right moments, from using its turbo boost function to get away from Sakura to using its eject features to send Blue Ink towards her brother's destination.

## Appearance

Aside from being described as a young man close to Blue Ink and Byakuya's age, Hiroyuki has no other description in the *Togami* trilogy. His Kagami Family Saga artwork depicts him as a young man wearing a white print shirt, long pants, and slippers. His eyes are covered by his dark hair, which is short and messy.

## Personality

Describing himself a trickster, Hiroyuki contrasts his sister by being very expressive and upbeat, even to the likes of the cold Byakuya Togami. He's a young man that loves to talk, often rambling or giving quips either about the situation or, more often than not, winds up speaking on something loosely/not related (much to his allies chagrins). His nonchalant attitude persists even when faced with major danger, thus allowing him to not be fazed easily (such as having the likes of having the world's strongest human after them). However, this could also lead him to not inform his allies about any potential dangers or even forgetting to take action when it's most needed. He's not above teasing those he likes and even calls himself a 'suck up to his betters' once paid sufficiently.

Hiroyuki, befitting of someone that works in the underworld of society, doesn't have much cares for respecting certain laws, especially concerning underage smoking or drinking. He's quite knowledgeable concerning pop culture, literature and even geekier topics, with the literature aspect he attributes to reading in a library when he was younger. Despite his easygoing nature making him seem dismissive of others feelings, Hiroyuki is quite caring for his allies and especially his sister, wanting to cheer them up when they're down. He holds the belief the world is too chaotic for any one organization to just control and that people should always be skeptical to what they're told. Hiroyuki doesn't hold himself in high regards, ultimately seeing himself as someone who can never be a 'star'. Instead, he opts to prop those who could be one and, even in his final moments, his last words was to wish his longtime companion to simply be herself in the end and hint at the one who could give her answers to her plight.

### Yuika Ketoin

Hiroyuki's older twin sister and someone who he deeply cares about, with both having a close bond with each other. When Byakuya insults her during the 'Taeko Stuck in Window' incident, he defends her oddball nature from him. When she gets kidnapped by the Hasegawa Research Institute he becomes quite worried, though tries to hide it with his easygoing attitude. Even when he reunites and eats with Blue Ink in their hotel room, he notes he can't be too happy since his sister is still missing. Due to the brainwashing she recieved by the Hasegawa Research Institute, Yuika's bond with her brother was gone and she had no problem in gunning down her brother, prior to shooting at Blue Ink. With the reveal concerning the K2K System's unreality, its unknown if the two of them were ever actually siblings.

### Blue Ink

During the first volume, Blue Ink rather disliked Hiroyuki due to his rambly, teasing nature and how his seemingly inability to take their situation seriously. It was to the point that he actually did get her mad enough to finally tell him to shut up. In contrast, Hiroyuki very much liked Blue Ink, often being friendly with her, complimenting her and even trying his best to cheer her up for when she grew upset, such as their last meeting prior to getting back together at the UN convoy.

In truth, Hiroyuki was Blue Ink's forgotten, long-time companion. He held quite amount of faith in her ability to get things done and openly wished that Blue Ink would eventually go back to being herself. In turn, Blue Ink grew more and more upset over realizing she had a friend that she could not remember, begging for him to finally tell him who he was prior to Hiroyuki getting shot.

### Byakuya Togami

Like with most of his relationships, Byakuya did not think highly of Hiroyuki, often insulting his conglomerate by calling them third-rate and even was willing to dump beer on his head when provoked. Despite being insulted, Hiroyuki tried to stay upbeat, though during the attempt to escape from Sonia and Kazuichi, he did snap at Byakuya for still insulting his conglomerate even then.

**Enemies**

### Taeko Kanai & Hasegawa Research Institute

The Hasegawa Research Institute was the enemy to the Ketoin Conglomerate, though Hiroyuki usually kept a casual attitude when it came to their antics. Taeko was secretly a member of the Institute, but Hiroyuki knew she was a spy and thus didn't mind making fun of her whenever something unfortunate happened to Taeko. While she didn't know her identity was compromised, Taeko did speak to Hiroyuki much harsher. When the Institute kidnapped Yuika, he was quite worried for her, even though he tried not to let that show.

### Despair High School

As the instigators behind the World Domination Proclamation, Hiroyuki is opposed to them as a member of Team Byakuya, often working as their getaway driver to avoid being captured or killed by Despair High. When they tried to look up information on Hiroyuki, Ibuki Mioda ended up admitting they had no clue on the actual identities of either him or his sister.

## Trivia

* Of the Kagami Family Saga cast introduced in Volume 1, and not deceased in that volume, Hiroyuki has the distinct honor of not showing up in volume 2 in either the flashback to the Legacy Crown Championship or the present World Domination Proclamation.
