Last Period: Owarinaki Rasen no Monogatari

The villains in A Last Period are like Jesse and James combined with Team Skull. Kinda like Pokemon the villains are lovable comic relief. Both shows are closely based off of a game but make up their own plot.  

Parodies of the RPG genre are commonplace, but both Senyuu and Last Period are stand-out examples of how to do them right. Neither of them have a major focus on story, instead opting to be entirely gag-focused series. Each show focuses on a different subgenre; Senyuu being a parody of traditional JRPGs and Last Period being a parody of the free-to-play mobile game model known as gacha. They both also poke fun at anime tropes and various other aspects of pop culture. 

Light-hearted parodies of mobile games that are also advertisements for their own mobile games, set in fantasy worlds and with a self-aware humor. Last Period has a collaboration with a very famous franchise, while in Hagane Orchestra they cosplay as characters from famous franchises. 

Weird parodies of classic RPGs and fantasy games, with a self-aware sense of humor and constant fourth wall breaks, frequently commenting on the nature of the genre and the industry. Both focus on a group of four characters that work for someone and are trying to make money, with limited and simplified animation, but still usually entertaining. 

Bad english ahead. Last period in comparison to Merc Storia is a little more fast paced. In the two animes the party goes from town to town solving other people problems in a very comedic and heartwarming way, very cute and childish. There are cute monster jumping around and messing things up.The mc in both series also quite similar physically. Even the pastel colors used are similar to a point.  

Both come from smartphone games. Both take place at a broken guild with adventures looking for money to re-establish the guild through silly adventures and ideas.  

Both are mobage adaptations with a great sense of humor. Million Arthur isn't nearly as wacky or meta as Last Period though, but both shows are pretty similar humor wise and are really enjoyable for being schlock. 

Hear me out on this. While these two shows have very little in common, if you enjoyed the gacha episode in Odd Taxi, you will enjoy Last Period, a show entirely about the ills of gacha. Shows critiquing the very nature of gacha is incredibly rare, and both shows do portray the declining sanity of the gacha addict very well. Also Hanae Natsuki is the MC for both. 

- Both series are breaking the Fourth wall - Both series give other anime reference and memes The difference is Animegataris is about people talking about anime. Last Period is about people questing and rolling Gachas.
