Cheating Is Just the Archer-Class Theory

“Senior! I just saw Mr. Gojo (First Ascension) being chased down the hallway by Miss Jeanne Lily, who was jabbing at his butt with a spear with astonishing enthusiasm. What happened?” “Oh, he stole the special treats prepared for Nursery Rhyme’s tea party.” “(Cute junior’s confused portrait.jpg)?” “Then I gave Jeanne Lily a Sweet Crystal (Invincibility-Piercing Craft Essence).” “I see. No wonder Mr. Gojo took off running with the same astonishing enthusiasm.” “By the way, Senior, what are you and Miss Jack eating?” “The unfinished treats Gojo had to abandon while being chased by someone with class advantage and Invincibility Pierce. I’ve already asked Emiya to make more for Nursery Rhyme.” “Nom nom.” “Want some, Mash? I’ve got enough left for one more bite!” “...Senior, I feel I should mention that Mr. Gojo just ran a lap around Chaldea’s corridors and is standing right behind you.” “...Ehehe☆.” Premise: Archer! Please land!
