The Strongest Outcast Prince's Secret Schemes for the Throne

Finally watched it lol It wasn't airing on TV, so I started watching it on Amazon Prime. (I'm only up to episode 5 so far) It's about the 7th prince, Arnold, who pretends to be incompetent. He secretly works behind the scenes as the SS-class adventurer "Silver," using his overwhelming power to help his outstanding twin brother, the 8th prince, Leonard, become emperor. The anime is about his schemes. Because the 1st prince (the crown prince) suddenly died, there's a succession struggle. The two in weaker positions do their best not to be killed (the prince doesn't want to become emperor himself, lol) - that's the gist of it. He seems to be flirting a lot with Fine, the daughter of the ducal family who supports Leonard... but well, he's scheming lol. (Since I've only seen up to episode 5) I'm finding it quite enjoyable! I plan to watch the rest tomorrow or the day after. Personally, whether he's Arnold or Silver, the accompanying old butler, Sebastian, is my favorite part. A butler with two faces: "Omnipotent Butler" and "Masterful Former Assassin." He's absolutely wonderful♡
