ところで草太君の通ってるこの塾——ホント名前どおりのコワソーな塾ね!
Tokoro de Sōta-kun no kayotteru kono juku—— honto namae dōri no kowasō na juku ne!
By the way Sōta-kun, is this cram school you’re studying at—— as hellish as its name suggests?
Ā!“Gokumonjuku” daro? Honto wa gakumon o kiwamerutte iu imi no “Gokumon” rashiin dakedo anmari Suparuta nan de kotchi no “Gokumon”tte kage de wa iwareterun da!
Oh! You mean “Gokumon Cram School”? “Gokumon” actually means something like ‘studying to extremes’, but people just go with “Gokumon” as in ‘prison gate’ because of its harsh conditions!
