It occurs to me that she would have one way to survive.
"So Hazou, how long would this firestorm last?" Keiko asked.
"About thirty seconds, why?" Hazou replied, looking suspiciously at Keiko.
"I see. Please proceed," Keiko said.
"...are you sure?" Hazou asked, his tone incredulous.
Keiko only gave him an impatient glare. "Now, Hazou."
"Uh, alright." Hazou smoothly activated and threw the tags. Keiko quirked her lips slightly, and then the air twisted and she was gone as she reverse summoned herself, doubtlessly already counting the seconds on the other side.
"Oh. Shit," Hazou said, beating himself up for missing that before hastily activating Hiding Like a Mole Technique to get out of the impending blast himself. It wasn't a complete loss, he supposed as he dived into the dirt. The massive explosion should make for a spectacular show. He just hoped he wouldn't get kidnapped and tortured for the secret of how he did it.
