What does a bunch of 27s mean in Tutor?

27 is a character code (code source: ツナ; Tsuna, tsu(2, Tsu is the Japanese pronunciation of the English word two) na(7, pronounced nana in Japanese) or the number 27 on the glove in an inanimate state, which was also written on the earphone given by Johnny Er later, so it is 27).
