it means hokago té time (after school té time)=H.T.T

Ho Kago té Time
why tu ask this?

HO-KAGO té TIME!

As fans have stated already, it translates as

"Houkagou té Time" o "Hokago té Time"

The first is the literal spelling of the kanji of 'houkagou', but there's other ways of spelling it, and the covers call it Hokago most of the time.

hou kagou té time :) o ho kago té time

hokago té time

Hokago té Time = HTT

H.T.T as in Ho kago té time /after school té time duh....

the answer is high school té time
