Takaki, Yuuji, Tamaki, Komaki and the rest of the gang are back, and ready for more adventures. Yuuji is aroused - err, thrilled - to have a new maid robot named Ilfa in the house, and tries his best to take as many perverted videos of her chest and nether regions as possible; the girls take a trip to the beach, where more videotaping is attempted; and everyone works hard on getting the school’s festival planned and running. It’s all in a day’s work for this group of friends!
On its way to Kure Port, the Amanohara stops at an island to be repaired, giving some much needed rest and relaxation for Shintaro and the Raimu unit. The backdrop of a gorgeous festival is the perfect diversion for Momen, Asa and the rest of the girls; they use their womanly assets to their advantage time and time again in an attempt to finally get to their beloved teacher. But amidst the shared baths and nudity galore, trouble is brewing... for a sinister figure from the gang's past is soon to attack and disrupt their newfound vacation.
To Heart 2 OVA and the Raimuiro OVA are equally as vacuous and pointless, revolving almost solely around the perfect panty shot or variety of engorged breasts. Neither is terribly humorous or anything of substance. Only the addition of ten minutes of random action and plot distinguishes the Raimuiro OVA from To Heart 2 OVA.
