Harem Camp!

A solo camping trip gone sideways leads to Kensuke sharing a tent with four girls on what was supposed to be a quiet trip into the woods. One night, cramped quarters, and a lot of awkward proximity later, he shows up to his first day as a substitute teacher and realizes every single one of them is sitting in his classroom. That's the setup, and the show leans hard into how uncomfortable and chaotic that situation gets. It's an 8-episode ONA from Studio Hokiboshi based on a manga, so it moves quickly and doesn't waste much time on slow build. The camping backdrop is a genuinely fun touch: it gives the early episodes a looser, more casual atmosphere than your typical school-setting hentai, and the four girls each have distinct enough personalities that they don't blur together. If you liked Laid-Back Camp and ever thought it needed a much more adult edge, this scratches a very specific itch. Or if Hybrid x Heart Magias Academy Ataraxia Specials was your kind of thing, the comedic tone here will feel familiar. It's not trying to be anything deep; the premise is intentionally ridiculous and the show knows it. What it does well is keep the energy lighthearted rather than mean-spirited, which makes the whole thing easier to sit with than you might expect going in.
