Beryl Gut (ベリル・ガット, Beriru Gatto?) 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 was formerly one of the forty eight Chaldea Master Candidates and a member of A team.
Sometime in his past, he broke into "that man's" treatment room, where he was driven out by a Doctor. Not much is known about this incident though, with Beryl saying it's been one of his happiest memories.
Beryl has black hair and wears glasses. He also has very sharp features and wears a black shirt and red pants.
Beryl appears to be rude and aggressive, appearing very carefree and mocking in his actions and attitudes towards the other Crypters. He is very happy about the second chance of life he has been given, along with the other Crypters. He is also quite cruel, claiming that killing and taking is the pleasure of life.
Beryl seems to care quite a bit about Kadoc, claiming that he thinks of him like a real little brother and truly cares for him. He also seems to be on friendly terms with Daybit. Beryl also acts somewhat disrespectfully towards Kirschtaria, the leader of the Crypters.
Arc 2 Prologue
After the events of Epic of Remnant, Beryl has woken up. He is one of the Crypters, who attempt to regress the world back into the Age of Gods, through establishing Lostbelts. Beryl himself oversees the sixth Lostbelt. 
Anastasia: Permafrost Empire
Beryl participates in the meeting between Crypters, held after all the Lostbelts have been properly established. Beryl, however, is critical of the situation, claiming that none of them have really done anything yet. He also complains how the Lostbelts of his and Daybit's are terrible for their purpose, saying that Kirschtaria will naturally be the one whose Lotsbelt will be the last one left and devour the other Lostbelts.
As they discuss Chaldea possibly entering the Russian Lostbelt of Kadoc Zemlupus, Beryl offers Kadoc his help, though the latter declines. As the meeting ends, Beryl returns to his Lostbelt, telling the others to inform him if an SOS-message arrives from Russia, claiming to really care about Kadoc.
