Nikki becomes the first member of the Tsukasa Empire to convert to the kingdom of science. Meanwhile, with Chrome in mortal danger, Senku and the kingdom begin plotting a way to bring him back to safety.
If you hand us Senku's head, I can 
promise you all the flame tests
إن سلّمتنا رأس سينكو، فيمكنني أن أعدك بكلّ تجارب اللهب
Si nos entregas a Senku,
Si nos entregas a Senku,
Si tu m’apportes la tête de Senku,
Se mi offrirai la testa di Senku,
Se me entregar a cabeça do Senku, 
prometo a você todos os testes de chama
