Seiji took the briefcase over to Peach-sensei's apartment and handed her two sets of personal barrier talismans along with the instruction booklet.
"Keep the talisman on your body, and then read the incantation…" Mayuzumi tried using the talisman after she read the instructions.
There was a flash of light.
"The barrier has indeed activated." Using [Astral Vision], Seiji was able to see a faint white glow on Mayuzumi.
"I can't see it…"
"This barrier is effective against physical attacks as well. Let's try it out."
Seiji asked Mayuzumi to bring him a broom. Then, he swung it at her using a slight amount of force.
*Smack!* The broom was blocked by an invisible power.
Seiji was clearly able to see in the field of his [Astral Vision] that a barrier spell formation had blocked his "attack."
They had now confirmed that the product they purchased was working properly.
