If you are looking for a charming, beautifully emotional harem slice of life romance anime that contains that old-school anime charm and cartoonish, expressively-animated humor that is missing in a lot of modern anime, then I highly recommend Da Capo. This anime will make you smile, but later on, will also make you cry.
This anime is not without its flaws, hence my score of 7.5. Even as far as slice of life shows go, the story of Da Capo is quite uneventful. You have your dedicated fanservice and tense, "titillating" moments, but this is not an anime where "eww, you pervert!" moments happen every couple minutes. Those who prefer a more gentle, organic pacing of naughty moments will appreciate this, but those who are bored easily will find it excruciating.
Despite this, the premise of Da Capo is rather interesting. A group of students live on a fictional island of Japan, where the cherry blossoms never wither. In this world, magic actually exists, and is the reason that the cherry blossoms are always in bloom, which are actually the blossoms of a giant magical sakura tree, planted there by a great magician. A handful of students find themselves in possession of their own magical ability. One can view other people's dreams. Another can read people's minds. One remains eternally young. However, while these abilities seem miraculous, the characters eventually come to suffer as their gifts eventually become their curse.
The focus and strength of this anime is not "what happens in the story", per se, but rather, the meaty, nuanced and deep emotional expression of the characters, and how they express that emotion as the primary romantic direction is established and each character's relationship with each other is affected. Mix this with masterful framing and a heart-softening OST, and you have a show that leaves a deep emotional imprint on its audience.
The beginning of the anime is where the majority of the fanservicey, comedic stuff happens, but once the romance plot really starts going, it's one continuous, subsuming experience that hones in on the single most important thing in a romance - the feelings of the characters. If pure, heartwrenching romance is what you're after, then this is where the simplicity of Da Capo's plot and setting becomes its strength. There is not much that distracts from the raw exhibition of love, jealousy and shame felt by the characters. Even the female characters that aren't the protag's choice get endings that leave you with either tears streaming down your face or with a tender feeling in your heart.
That's what this show is about - emotion, and the emotion rarely feels forced or abrupt. Just vulnerable, tender and thoroughly satisfying.
As for everything else...
In addition to the actual episodes, the lovely folks at Zexcs throw in a bunch of bonus content in the form of character insert songs that feature live action music videos by the female voice actors themselves, shot in a bunch of fancy, scenic locations. That, and 5-minute long "side episodes". These range from beautiful to...pretty bad.
There are also 2 entire filler episodes that are recaps and are literal time wasters. Not to mention, the ending is not exactly stellar, with the last 2 episodes feeling incredibly rushed and not quite giving a sufficient feeling of closure. This and the overall unremarkableness of the plot all contributes to my story score.
The animation, though dated and therefore inconsistent in places, is still pretty dang good for a 2003 anime. There are definitely anime from this era that have much worse animation. What the animation lacks in polish and high fidelity, it makes up for in the sheer emotiveness of the characters, both in comedy and in drama, as well as some nature scenes that are just eye-meltingly beautiful.
The music is arguably the best part of Da Capo. Yugo Kanno's score captures almost every aspect of romance perfectly, from having butterflies in one's stomach to elation and finally, to heartbreak, while Hikaru Nanase's lighthearted jingles do more than enough to capture the essence of the cheeky, comedic parts. This isn't even mentioning the plethora of vocal tracks, including the opening, which was parodied in legendary Kyoani slice of life anime Lucky Star.
The characters, while certainly not the most sophisticated or unique, are for the most part incredibly charming. Junichi, the main protagonist, though very much your typical male protag in many ways, has enough self-awareness and wit to not be entirely clueless or uninteresting. There is a good blend of female archetypes, and a good mix of rapport and mischief. Having said that, everyone that isn't the male protag or one of the main females is generally much weaker. Junichi, unfortunately, gets much worse as early as Da Capo Second Season (but that's beyond the scope of this review).
Overall, Da Capo is definitely not for everyone, even general harem anime enthusiasts. It's slow, uneventful, and a little dated. However, if you like animes that focus exclusively on emotions, then this anime is more than worth the watch, even with its obvious flaws.
