The five new members of the Earth Defense Club are relaxing in the Kurotama Bath when they encounter Karls, first prince of Honyala Land. Karls wants to rule Earth in a "happy" way, and recruits the Earth Defense Club to help him -- by making them his personal knights!
But one day, I became unhappy.
لكن ذات يوم، أصبحتُ غير سعيد
Aber eines Tages wurde ich … so.
Pero un día fui infeliz.
Pero un día fui infeliz.
Mais un jour,
je suis devenu malheureux.
Ma un giorno, sono diventato infelice.
Mas um dia, eu fiquei infeliz...
Но однажды моё счастье меня покинуло.
