Illusionary Ability

"Now then, we'll start the mock battle. Both sides, materialize your Device in illusionary form."

"Come forth, Intetsu."

"Serve me, Lævateinn."

She was made light of. Thinking of that action as insult Ayase flexed her limbs. One does not receive any physical damage if she is cut by a Device in Illusionary Form. Only her stamina gets depleted. Ayase had confidence in her stamina, to the point where she can easily keep up with Ikki and Stella on their morning runs. A fatigue of this level did not mean anything to her.
"…Huh?"
That's how it should have been… but she could not feel any power in her body.
