Xuanzang's Captivating Cheeks! (Patreon)

Tomorrow is the start of the next Grail Front! a new training program designed to give the Last Master of Chaldea some experience in a actual Holy Grail War. In preparation Da Vinci Collaborated with a few of Ritsuka's long time servants to improve of few of their more underwhelming skills, excited to show off this new "Rank Up" is one Xuanzang Sanzang! Without hesitation she runs to Ritsuka's quarters to show off her new "Captivating Rosy Cheeks!" equally excited to see the skill in action he proposes a quick trip to the simulator room for some last minute training for tomorrow's events. Unbeknownst to them both this new Rank Up had some unexpected effects and Ritsuka finds himself captivated by another set of cheeks! He'll at least be able to go into tomorrow's battle with a clear head...even if he's a little exhausted.
