[2] Borja Casillas Toledo attended the University of Las Palmas de Gran Canaria, where he received a degree in Early Childhood Education.

[3] In 2017, Sethlas won the nineteenth Drag Queen Gala of the Carnival of Las Palmas de Canaria, with the concept ¡Mi cielo!

[6] In 2017, Sethlas was sued by the Association of Christian Attorneys (ACA) for using religious symbols in his performance at the Carnival of Las Palmas Drag Queen Gala.

"[7] Monsignor Francisco Cases Andreu, bishop of the Roman Catholic Diocese of Canarias (Las Palmas Province), compared the drag queen's performance with the Spainair Flight 5022 accident, affirming that the former was making him "live the saddest day" of his stay in the Canary Islands.

"[9] Borja Casillas faced two lawsuits accusing him of wounding religious sensibilities,[10] one of which was dismissed by grand jury number 8 of Las Palmas, given that "a party like the Carnival allows us to rule out a deliberate intent to offend".
