[Keishikin] Moto Teikyuu Mazoku no Isekai Shoukan (SCANMTL)

A student in a gym uniform accidentally triggers “Summoning by Illusion Difference,” opening a fissure that releases enormous, glossy tentacles into an ordinary world. A towering creature enfolds her in its slick body as her clothes animate, her hair is dragged into a hungry mouth, and her body swells through a bewildering metamorphosis. Her blush and protests bring moments of awkward comedy, while the recurring lines “This... it’s moving!” and “You’re too valuable to ruin” sustain the nervous tension surrounding her transformation.
