THIS BOY IS A PROFESSIONAL WIZARD is one of the four short stories directed by Soubi Yamamoto. The stories each have around 30 minutes of screen time, and they tell a story that might just be deeper than what it really shows.
And maybe not, maybe it's just a BL. You have to take what you want from it.
As the story goes, we're met with Chiharu Kashima, a wizard, sitting alone at the bar, when suddenly Toyohi Utsumi comes in his life with a love confession that leaves our wizard boy puzzled. They start hanging out, have a cute date watching jellyfish swim, go out drinking... and when an accident happens, we get to see a different side of our professional wizard...

Do you love Kashima-san, the wizard?

I usually don't write reviews, but this anime hit a little close to home. In other words, the main idea of This boy is a professional wizard is You're your own worst hater, enemy. which can be also translated to You're being too harsh on yourself, take a deep breath and love yourself.
I struggle with self love, and that's the reason I don't allow myself to love anyone and push away those, who try to love me. In the last episode, it was painfully clear that Chiharu Kashima fights with dark thoughts of not being enough, believing that only magic (and his skill in it) defnies him as a person,defines his worth.

But I'm nothing if I can't use magic!

Thankfully, Toyohi Utsumi is there to show him, that he is so much more than just that. I could relate to the feeling of being loved not for yourself, but for your abilities or something, that makes you worthy in the eyes of others... Even though the animation was... not quite bad, but it's hard to call it an animation and the story itself was divided between 4 8-ish minute long episodes. it carried a deeper message, and I am glad I gave this anime a shot.
But given the anime itself... I did not care about the kiss or Toyohi Utsumi. I did not care about the backround and it did not made me want to read/see more.
The art was beauitful, I liked the voice acting (the emotions didn't come off as cringey like they use to in BLs)... So overall, it makes for a show that is not hard to watch or finish.

I love you, for you.

That given, it's your choice if you want to give it a shot. I would not recommend it, but I would also not not recommend it. My rating for This boy is a professional wizard is 5/10. Points were given for story, art, music, pace, voice acting and voice actors and characters. But as it didn't leave the impression of something memorable, the score stays "low".
That is just my opinion though, so if you liked it more or less, I understand both cases. For me as an amateur, this is all I can offer.
It's strange how much emotion you can stuff in 30 minutes...
