While taking their usual bath, the boys discuss how much Kyotaro is like an old man. The next day, when they go to school, they find themselves exhausted by climbing up the stairs... and learn that they're all becoming old men!
You've become even more of an old man!
!أصبحتَ عجوزاً أكثر من السّابق
Du bist total antik geworden!
¡Te hiciste más viejo!
¡Te hiciste más viejo!
Sei diventato ancora più vecchio!
Você virou mais do que um senhor de idade!
Ты ещё сильнее постарел!
