I actually can't remember what made me want to watch this, but it's just adorable and funny. I'd end my review there, but there's a lot more to talk about than just saying it's adorable and funny.
When I got into the first few minutes of the The Royal Tutor, it felt like it had some Diabolik Lovers vibes going on, but fortunately this proved to be wrong. Not that Diabolik Lovers is a bad anime in my opinion; the characters could have been fleshed out a bit more, and for me it was curiosity that made me watch the entire series. But we'll get on to this topic in a sec.
Anyway, we have Heine Wittgenstein, who has been personally appointed by the King of Grannzreich to tutor the four younger Princes so they're worthy of the throne. He's so adorable in that he's short and makes jokes/remarks with such a straight face and turns chibi at the right moments. And this starts from episode 1 too so good times come early for us.
So we meet the four Princes with Heine, and this is where I got the Diabolik Lovers vibes. We have Kai, the silent but evil looking type, Bruno, the glasses-wearing brains of the four, Leonhard, the athletic type, and Licht, the youngest and outgoing type. From being introduced to them, I was thinking that the Princes are similar to the Sakamaki brothers with their distinct personalities, but I am so wrong about this because the Princes are different and so much better than them. The Sakamaki brothers were the whole "what you see is what you get", when we were introduced to them and seeing them individually when Yui (the MC) met each one separately. Except for Ayato who seemed to be much more interested in Yui than the others. But Diabolik Lovers had a lot of potential by fleshing out the brothers more with their distinct personalities, which is where is lost out. Fortunately, The Royal Tutor used their personalities to flesh out each Prince more thanks to Heine using his skills and knowledge as both a tutor and commoner to help them develop into the Kings they want to be and the type the citizens of Grannzreich need; there's much more to the Princes than meets the eye here.
Not only is the character development great, but so are the story and plot. As you get into it you do notice that it is a pretty lighthearted series with its comedy and chibi moments. At times like this you assume it'll be like this throughout, but I am glad it wasn't. A few episodes in and there are plot twists which take the story on a darker turn that comes in each episode thereafter. The delivery is excellent as it helps bring out the reality aspect in that not everything is at it seems in a person and, if revealed, can affect the reputation of a person, especially if they are high-profile. Fear not, because it doesn't get too dark, just that the events could have a potential impact in the Princes' legitimacy to the throne. Here we get to learn even more about the Princes, which is where further character development comes into play, and how Heine's involvement is essential and helps the Princes learn to make decisions as future Kings. These moments are a perfect balance to the lightheartedness, making The Royal Tutor one to watch.
It is a shame that there are only 12 episodes out; I wish there were more. Hopefully there will be a Season 2, but there is a silver lining in that The Royal Tutor has very good replay value. Overall it is a well executed anime with adorable characters that develop throughout the series, with twists along the way that help keep the story interesting and allow for further fleshing out of each character with emotional scenes and what not.
Definitely one to watch!
