A hot spring con that exists purely so the show can watch Bell get dragged through absurd situations and come out confused. The comedy timing is so tight that the fanservice stops being fanservice and becomes the punchline. This OVA knows exactly what it is: a 45-minute joke that works because everyone commits to the bit, from the suspicious Familia rivalry to Bell's complete inability to catch a break.

Bell finds himself roped into another scheme when a natural hot spring suddenly appears in Orario, courtesy of the Dian Cecht Familia. What should be a blessing for the city quickly becomes suspicious when Naaza from the Miach Familia smells a setup. She believes the whole thing is an elaborate con, and she needs help to prove it. Caught between two competing Familias yet again, Bell ends up in the middle of their long-running rivalry simply by being in the wrong place at the wrong time. This single OVA episode blends comedy and ecchi fun with the fantasy action, adventure and romance the franchise is known for.
