If you like Saiki K you'll like:

TLDR: If you liked Saiki watch, The Daily life of an Immortal King, Mob Psycho, Mashle, Life Lessons with Uramichi Oniisan, Gintama

Howdy I decided to create this list of shows that remind me of Saiki K. While not completely the same each show has some kind of similar aspect. Saiki K is one of my favorite shows in existence, (Idk who i was before December 28 2017) and nothing has quite ever scratched my itch like this show does but these shows have a similar feel.

1) "The Daily life of an Immortal King." Wang Ling is basically Saiki just in a different font. Just about everyone in this society has powers however his powers are extraordinary. (He doesn't want them to be). He's literally God Like but just wants to live an average life. I'm ranking this one as close to Saiki K as possible. The main differences are like I said this society does run on magic so everyone has powers but Wang Lings powers are like God Teir and everyone thinks he's a loser. TDLIK also is more modern in its references, like literally on episode 2 we get a how to basic reference. Very LOL. The humor is similar, the animation is very pretty, the characters are all likeable. There is romance but not overwhelmingly so, and this show has a bit more fighting. The show is originally in Mandarin but the English dub is nice imo.

2) Mob Psycho 100. Of course a classic. Mob Psycho follows Mob another OP psychic as he learns to deal with his emotions (and hopefully doesn't go 100%) It's more of a coming of age story imo but the humor elements are still there. I personally didn't like it as much (irdk why) but If you like Saiki I feel like this could be a 98/2 situation because all my other friends loved Mob Psycho.

3) Mashle: Magic and Muscles. Regularly slept on by Saiki fans but Mash lives in a society where everyone is a magic user... except him, so he basically just works out and becomes extremely over powered. The humor is there the characters are loveable, and The love for a sweet treat is also there. Coffee Jelly 🤝 Cream Puffs. I love Mashle.

4) Life Lessons with Uramichi Oniisan. This show follows an ex Olympic level gymnast and his daily life working on a children's TV show. He's cynical, and over all depressed and over it. This show is a comedic slice of life and the humor definitely is a bit more dry than saiki k but I still love it.

5) Gintama. The OG the humor is fast paced witty and loveable. Not much else to say. I love Gintama. Please watch. Thx ily.

6) Sakamoto Desu Ga. Sakamoto is somehow the coolest guy ever always getting the ladies. This makes the other guys sick leading to them pulling pranks on him however Sakamoto always wins.

7) The Melancholy of Haruhi Suzumiya. Haruhi is a very odd and eccentric girl and she proves to be troublesome for Kyon her classmate.

Honorable mentions: Ghost Stories Dub, One Punch, Way of a House Husband.

So feel free to add to my list but these are just some shows I really like that remind me of Saiki and I hope you guys give them a watch! <3
