Now that Well and the others are 15-year-old adults, they officially form their adventuring party, the Dragon Busters. However, before they have time to enjoy adventuring they receive a mandatory quest from the kingdom and venture deep into ancient underground ruins that no one has yet to return from alive. Well and the others are transported deep underground by a trap, and what awaits them there is...
Where are the adventurers 
who never returned?
أين هم المغامرون الّذين لم يعودوا إطلاقًا؟
Wo sind dann
die verschwundenen Abenteurer hin?
¿Dónde están los aventureros perdidos?
¿Dónde están los aventureros perdidos?
C’est vrai,
où sont passés les aventuriers ?
Dove sono gli avventurieri mai tornati?
Onde estão os aventureiros
que nunca voltaram?
Где же те авантюристы,
что не вернулись?
