Samantha's suggestion sounded too simple to be reliable, but people still listened to her since Manjimania was almost upon them.
Dura felt something was off about the plan. In her view, the demon would eventually target the strongest wizard in the group, which was definitely not her, so accepting the strategy should be fine.
Seeing Dura indecisive, Samantha yelled at her, "What's your problem?? We're going to draw it away from our base AND help you get rid of it. Or do you actually want to see the base destroyed, huh?!"
"Fine. We each try our best to weaken it. Whoever becomes its last target should be the guy who'll take it farther." Dura glanced at everyone with a hostile look. "By 'our best', I expect you all to use everything you have. Don't hide your sh*ts back…"
By this, she wanted one of the others to draw Manjimania's enmity so that she could escape.
