"Well, now that the week has started again, I should probably go back home and prepare lunch right away…" Elayne thought, making her way back home after leaving her daughter in high school.
"Ah, maybe I should go meet Mark first? I wonder if he-"
TRUUUUUMMM…!
"Huh?!"
She immediately heard a huge explosion, glancing behind her, only to see a huge wave of darkness and mana surging from within the high school building, rapidly moving into the skies and forming an arc.
"W-Wha…? Elena!"
Without hesitating any other second, Elayne immediately started running back into the high school, finding a lot of commotion everywhere as people started running away from the building, the darkness continued spreading out, appearing outside the building already.
"R-Run! Evacuate! A Dungeon Break has appeared inside the school!"
"Monsters! I saw monsters appearing!"
"They're inside the building! Call the police! Someone!"
"They're already coming here!"
