Classroom☆Crisis

Sci-fi, futuristic settings. Main characters are charismatic, manipulative assholes who struggle against authority figures (inter-family, brother/brother rivalry a common theme). Both MC's set themselves up as the villains for an ultimately good purpose.  

- Vain but skilled highschooler in managerial position - Budgeting and management of a poorly run team/business - Colourful and moe Classroom Crisis is ever so slightly more mature in its approach with believable scenarios and reasonably realistic characterisation. Amagi Brilliant Park on the other hand, is just a massive power-trip for the incredibly intelligent MC, where everyone else is more or less an accessory to his brilliance as oppose to being characters with their own reasons and motives. Taking the above bullet points into account; go for Amagi if you want OP MC + cute and silly, go for Classroom Crisis if you like drama and plot-twists. 

Strong engineering theme present in both animes. Both are centered around a group of students. If you're looking for a sci-fi/tech related anime both are really good. Both are motivating and fun animes to watch if you're an engineering or computer science student. 

Really strong sci-fi/tech/engineering theme present in both. Both are futuristic. Group of tightly knit people working for a common cause. Theme of strong perserverance also present. 

- You can learn a lot about these animes, the two are not limited to make big money orders they want, if not explained in the Classroom If a company's dealings C:TMSP and economic theory. - Romance is slight and slow, but take time but you can see a romance that fits well with the main story. - The drama, how you feel, how mistreated they are the main characters. 

- Male MC are cool, calm & calculating - Female MC is persistent, strong & very much in love with the Male MC - Male MC appears to be cold but in reality wants to be helped - Female MC wants to save the Male MC while everyone else doubts him - Best friend of Female MC has a connection with the Male MC - A group of tech savvy people closest to the MC(in the case of 86 they are with the Male MC & in Classroom Crisis its the Female MC) - Lots of internal feuds & hatred towards the MC's little tech savvy group from the company/state that controls them whereas the other MC is at a high position in that company/state & tries to save them - Mecha/Robot theme as a major part in the story & similar songs & soundtracks They have to be 2 of my favorite series because of the way the relation between the Male & Female MC & their characters in general are very much to my liking(especially the Male MC) read more 

The main character in both anime has one goal. To take revenge on someone Although the genre and other things are completely different this is the closest I could find to 91 Days so far. 

Groups of people chilling (but not really), learning about teamwork, and building mechs. RoboMasters is set in university and is based on the irl competition RoboMasters. Classroom Crisis is set in the future with space drag races, big bucks, and big dramatic plots. CC is grander in scale whereas RoboMasters is essentially a down to Earth school club show with cute little robos. Neither are life-changing masterpieces and neither stands out much over the other execution-wise, both are enjoyable but underwatched. If you liked one, give the other a try. 

Genre-aware: Classroom Crisis is a mecha anime at its core, but most mecha anime generally neglect the huge costs behind building these massive robots and the financial implications, so this is what it hones in on. Grimgar is your standard trapped-in-an-RPG-world anime but it focuses on the players who suck and how they get by, the realities of endless grinding and slow levelling. Fanservice: Plenty of jiggling. Although, both series make some attempts at equal gender fanservice. 7/10 for effort. Realistic behaviours and reactions around romance: More or less... It's an anime after all. While there are characters who stray from this point, most characters in both actually do a pretty good job of acting like real people when it comes to love/lust. read more 

Neither Stellvia nor Classroom☆Crisis begins its story with a clear view of the main conflict of the plot, yet both series use strong character development to slowly build a compelling drama. The futuristic classroom setting of both series also allows for a fair amount of slice-of-life episodes, allowing for a controlled pacing of the story rather than plunging straight into overly dramatic scenarios. 

Both sci-fi anime (which are completely original) take place in the future and involves a group of people working in a company (making androids in Plamemo, spaceships in CC) Both have its share of comedic, dramatic, and romantic moments (Plamemo being more of a romance) 

After wathing CC first episode a strong similarity to Durarara hit me! In my opinion it has the same kind of crazy atmosphere were you need to focus to understand the plot!-this is my strongest point on their similarity-!!! The music is also somenthing that remimded me of Durarara!...jazz touches and stuff that perfectly fit the anime's scenes! 

Both are sci-fi original anime which include white collar workers dealing with new innovations, research, politics/economy. Both are also somewhat misleading in what they end up being: Classroom Crisis' first episode looks like an average cliché Sci-Fi action high school teenager you-can-do-the-impossible-if-you-only-want plot convenience story only to walk away from that considerably to almost completely by the second episode. Kado completely walks away from its build up by the last 2-3 episodes into a you-can-do-the-impossible-if-you-only-want plot convenience story. 

Both are relatively near-future sci-fi series that are heavily character driven with particular emphasis on the strengthening bonds among a group of individuals as they work towards a common goal.
