Sorcerous Stabber Orphen: The Wayward Journey Volume 15 by Yoshinobu Akita

The chaos in Urbanrama that began when Orphen's group arrived has reached its peak. Doppel X has bared their fangs at Orphen, Majic is missing, and Claiomh has become Sleeping Beauty, her mind closed off. Even if Orphen triumphs over the Red Dragon assassin Helpart, the Green Gem Armor worn by Ryan Spoon has turned the whole south of the town into a sea of trees, and a Deep Dragon has appeared in the north. Trapped between these two threats, Urbanrama descends into unprecedented panic!
