"What's going on?" Ritsuka immediately asked Shion.
"Just connect the inrō to your Mystic Code. The scan found nothing else inside it—only usable magical energy."

Not only had Ritsuka's Mystic Code been upgraded, but Shion had also participated in modifying Mash's exoskeleton armor. She planned to add the Celestial Longevity Armament she had yet to complete researching. Once it was finished, Mash's strength would undoubtedly rise another level.
