If you're looking for anime similar to Classroom of the Elite 2nd Season, you might like these titles.
In 2010, the Britannian Empire enslaved Japan using powerful mecha known as Knightmares; in the aftermath Japan was renamed Area 11, and its people began a hard and terrible existence. Lelouch, a Britannian student living in Area 11, has grown up hating the Empire and everything it stands for. One day, in the middle of a terrorist attack, Lelouch meets a mysterious girl who grants him the ability to control minds. Can he use his new power to fight for freedom, or will his hatred twist his good intentions into mindless acts of vengeance?
While Classroom doesn't have mechs and superpowers, both shows come down to one thing: Super IQ guy outsmarting everyone around him, and controlling situations from the shadows. I think if you liked the main character of one show, you'd like the other, and therefore enjoy both shows.
Both anime with main character controling all the situation in the shadow.
However, classroom is just normal person setting, but code geass is with supernatural and mecha and battle
Hikigaya Hachiman, with his unique thought processes, seemed to be glorifying the life of a loner when his guidance counselor, Hiratsuka Shizuka, talked him into joining the Service Club. Together with the other members, the breathtaking, flawless Yukinoshita Yukino and the cute, popular Yuigahama Yui, he spent his days solving all kinds of problems for his classmates, from relationship worries to running the cultural festival committee. The seasons have given way to fall, and now Hachiman, Yukino, and Yui are preparing for a field trip to Kyoto. What request has been brought to the Service Club this time?
Teenage angst is probably the best word to describe in what genre these two fit in. Many issues that could be solved by simple communication can get unimaginably awkward and tricky in the setting these series take place in. As opposed to the uncaring nature of how other high school students are portrayed, our protagonists get the unlikely role of helping others and solving problems (Ayanokouji helping Class D, Hachiman working in the Service Club) but they tackle it on their terms with Ayanokouji pulling the strings behind the people in his class that often results in a surprising turn of events in the favor, while Hachiman does things "his way" that at times involve self-sacrifice to fix problems. Nonetheless, some of their schemes include provoking others to achieve something, speaking bluntly, and exposing people's facades.

I decided to recommend both shows' second seasons not only because of the introduction of a character I deem similar to another but also because Classroom of the Elite season 2 is far more grounded than its predecessor which involved high schoolers surviving on a tropical island whereas most of the setpieces for s2 adhere to more realistic standards (well, as realistic as the hierarchical point system in a school could be). A huge difference between Ayanokouji and Hachiman's approaches is that the former views everybody else as tools, so even if it seems as though he does good deeds he's always thinking ahead and how it can benefit him in the future whereas the latter at times acts like a pushover for the sake of other people and is more emotionally involved with his friends and family. Both shows tend to get philosophical.
