Riku now realizes the scale difference between himself and Kyoya Kujo, who says he wants to protect the GBN world. As he wonders what he should do to get even a little closer to the champion, Magee offers to introduce him to a fellow Diver. Riku dives into the China-inspired world of the Estania Area to learn which path he should follow, accompanied by Yukki and Momoka, who now has an official account.
And if you know thy enemy as well,
you'll never lose in 100 battles.
وإذا عرفتَ العدوّ خير معرفة، فلن تخسر
في مئة معركة
Wenn ihr dann auch den Gegner kennt,
werdet ihr nie verlieren.
Si también conoces al enemigo,
nunca perderás en cien batallas.
Si también conoces al enemigo,
no perderás ni en cien batallas.
Si en plus, tu connais ton ennemi,
jamais il ne te vaincra.
Una volta fatto, conoscerai anche il tuo nemico,
E se conhecer o seu inimigo,
não perderá, mesmo depois de 100 lutas.
Если ещё и врага познать, 
то ты никогда не проиграешь.
