Hello everyone, both newcomers and familiar faces! It's me! I'm Rijinetta-san, the ultimate cute and smart beautiful robot girl! While investigating ruins on a deserted island, I learned a shocking truth and the existence of the culprit. Seriously! I only came for a vacation, and yet I'm on another big adventure! Thus, beyond the door of the ruins lay a barren wasteland, a world filled with a sinister atmosphere…

"So this is… the Demon World!?"

Connecting to the Demon World, what a thing to do! No wonder monsters are rampant! After overcoming numerous enemy encounters in deadly battles, I finally reached the deepest part! I'll give those who interfered with my vacation a harsh punishment! The door of the ruins, and the sinister Demon World connected beyond it. After overcoming numerous enemy encounters in deadly battles (H), what awaits at the end!?
