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 Greater History of Man 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 enrolled in the Clock Tower's Anthropology Faculty 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 plans to summon a Berserker-class Servant.[2]



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.[2]


Fate/Grand OrderEdit

Olga Marie Animusphere orders Team A to participate in "Singularity Point F".[3] With Lev Lainur betrayal, Daybit was amongst the casualties to be put into cryofreeze in their coffins.[4]

Arc 2 PrologueEdit

After the events of Epic of Remnant, Daybit has woken up.[2]

Anastasia: The Permafrost EmpireEdit

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 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 destroyed it immediately.[5]

SIN: Land of Unified KnowledgeEdit

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 in the battlefield with no weapon, like someone who doesn't have a sense of danger. 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.[6]

Yuga Kshetra: The Black Final GodEdit

Making his appeareance after saving his fellow crypter from an enemy attack, Daybit reveals his business in the Indian Lostbelt: To give him an advice about how to compromise a god's invincibility and to prove him that Koyanskaya can be contracted to travel between lostbelts without issues.[7]

Ancient Titans' Ocean Atlantis: The Day God Is Shot Down Edit

After Beryl's betrayal and subsequent murder of Kirschtaria Wodime and leaving the Atlantic Lostbelt, Scandinavia Peperoncino swore vengeance against the former and followed him to the English Lostbelt. Effectively leaving Daybit as the last remaining Crypter operating in his own Lostbelt.


Daybit is said to be an abnormal genius. Da Vinci mentions there has only been one or two people in life whose genius she acknowledged like she have his, and ‎Marisbury Animusphere valued his talents highly.[2] Although not shown in any great detail yet, his power and skill as a Master are proven extremely high, potentially surpassing Kirschtaria, by his acquisition of a Grand Servant.
