"Secret treasure?"
Lumi showed a confused expression:
"What secret treasure? Like the kind in the Underground City?"
The girl stood up, pulled her happily in a circle.
The light blue skirt blossomed like petals. She said mysteriously:
"I heard from an older student that there's a hidden treasure left by a certain generation of Hero Squad on a corridor in our Saint Louis Academy Library."
"It's said that if you can find that secret corridor, you can reach a mysterious space rarely visited by anyone. Lumi, come with me to find it!"
Lumi furrowed her brow and without hesitation chose to refuse.
Diana immediately showed a hurt expression, but Lumi remained unmoved:
"Diana, the secret treasure doesn't exist."
Diana said defiantly:
"How do you know the secret treasure doesn't exist."
Lumi pointed a finger at her forehead and then said:
"Every 500 years, the Dungeon requires heroes to form squads and go on expeditions."
