Daybit Sem Void (デイビット・ゼム・ヴォイド, Deibitto Zemu Vuoido?) is one of the seven Crypters, Masters attempting to supplant the Proper Human History with that of the Lostbelt in Fate/Grand Order: Cosmos in the Lostbelt. He is the Master of a Grand Class Servant. He was formerly one of the forty eight Chaldea Master Candidates and a member of A team.
Daybit is from Nevada in the United States of America. He enrolled in the Clock Tower's Department of Lore and was later expelled. Daybit joined Chaldea Security Organization, he became one of the forty eight Chaldea Master Candidates and a member of Team A. Daybit planned to summon a Berserker-class Servant.
Daybit is said to be an extraordinary person, that's why he will not try to understand anyone, nor will he ever be understood. The reason why the Servant assigned to him was Berserker was because there were no expectations of communication from the very beginning.
He considers Scandinavia Peperoncino a friend, close enough for Pepe to be fine with Daybit calling him by his birth name, Myourenji.
Arc 2 Prologue
Anastasia: Permafrost Empire
Daybit remains mostly quiet during the meeting with the Crypters. He agrees with Beryl Gut about feeling the pleasure of killing they couldn't experience in a coffin. When Kirschtaria Wodime reveals Chaldea is about to emerge from the Imaginary Numbers Sea, Daybit predicts they'll be in the Russian Lostbelt given the karmic bond between the Oprichniki that attacked them three months ago. Later, Scandinavia Peperoncino asks his opinion on the "cube", to which he responds by calling it a vulnerability in the Indian Lostbelt, and if it was him or Kirschtaria, they would have destroyed it immediately.
SIN: Synchronized Intellect Nation
Like with the first meeting, Daybit barely interacts with his fellow Crypters. At some point of the conversation, Wodime asks his opinion about Chaldea's master, to which he responds they are doing pretty well to be someone who stands on the battlefield without a means to protect itself, like someone lacking awareness of the dangers. At the end of the meeting, Scandinavia asks him about his feelings regarding Ophelia's death, to which he answers he wasn't very aware of her though he says he feels somewhat regretful about that before cutting the transmission.
Yuga Kshetra: Saṃsāra of Genesis and Terminus
He makes an unexpected appearance in the Indian Lostbelt, saving his fellow Crypter from a pinch and admonishing his Servant for his unnecessary judgement in a foreign territory. A surprised Peperoncino is unable to believe Daybit has traveled to India to help him. It was stated a Crypter can't interfere in the another Crypter's affairs, but there is no rule forbidding personal meetings, a loophole Daybit took advantage of to visit India, be it on a whim or due to fellowship. He reveals that, although somewhat expensive, Koyanskaya can be used to travel between Lostbelts.
Seeing Peperoncino without his assigned Servant and fighting alongside the enemy, Daybit is confused about what is going on and the details. Peperoncino reveals that there have been problems with the Lostbelt King, but since the one responsible seems to be one of the Alter Egos, he couldn't comment about that to Kirschtaria. Accepting the disagreements between the Crypter and the Alien God's emissaries, Daybit concludes that Peperoncino is not betraying his comrades. He changes the subject and asks if Peperoncino can defeat a god. Hearing the Crypter's answer about how futile it is to even try to do something like that, he advises him to change the way you can deal with one: if there is a need that must be met, then there is a way to sabotage said satisfaction. Upon seeing Peperoncino understanding what he needed to do, he decides that it's time for farewells, asking him to keep the meeting a secret from Wodime. Without saying a word, he gazes at Chaldea's Master for a few seconds before exiting the place.
Atlantis: Ancient Ocean of the Dreadnought Gods
Olympus: Interstellar Mountainous City
Following the events leading to the culling of the Atlantic Lostbelt, Daybit remains the last Crypter operating in his own Lostbelt.
Daybit is said to be an abnormal genius, worthy of acknowledgement by Da Vinci herself. Marisbury Animusphere valued his talents highly, and considered him to have the highest Rayshift aptitude of all. Among the members of the A-team, Daybit, Scandinavia Peperoncino, and Kirschtaria Wodime are ranked the highest in terms of fighting power and are considered more or less equal to each other so compatibility would decide the victor if they were to fight each other. In a simple duel to the death, Peperoncino would win, a frontal "war" would result in Kirschtaria's victory, and regardless of situation the one to ultimately win would be Daybit due to his unpredictability. Although not shown in any great detail yet, his power and skill as a Master are proven to be extremely high, potentially surpassing Kirschtaria, by his acquisition of a Grand Servant.

 Fate/Grand Order material VIII - CHARACTER profile: Daybit Sem Void, p.016 [T]
Daybit Sem Void
Born in: Nevada, USA
Talents: None in particular.
Likes: Unique people.
Dislikes: Nothing in particular.
A cool-headed young man, a little lacking in humanity.
Silent, emotionless and expressionless. All the right ingredients to ruin a conversation.
His no-nonsense attitude makes people describe him as “like a robot”, but it would be a lot more accurate to describe him as a game animal doing everything it can to survive. The simple beauty of the wild.
Marisbilly considered him the one with the highest Rayshift aptitude of all and his skills were also in the top tier among the Masters gathered by Chaldea, but due to his unsociable personality, he was given the role of supporting from the shadows instead of being the team leader.
Although the other team members acknowledge his abilities, his complete lack of cooperativeness made Wodime a preferable choice for the leader position.

TYPE-MOON Ace Volume 14 Nasu interview
Question: So does that make Peperoncino second to none in terms of combat prowess??
Nasu: Pepe would win in a simple 1v1 match to death, but Kirschtaria would be the one to emerge victorious in a frontal “war”. And regardless of the situation, the one to ultimately win would be Daybit due to his unpredictability. These three are more or less evenly matched, so winning boils down to compatibility. Assuming the two belong to the same category of strength, you could say Pepe is backward compatible with Beryl.
So we already know who would win if Beryl and Pepe were to clash head-on.
Nasu: That’s right. Beryl thinks he could kill Pepe in an instant if he wanted to, hence his arrogance. Meanwhile, Pepe, sensing what’s on Beryl’s mind, would just shrug it off like the adult he is. “Sure, if that’s what you think. You do you.”
