Most of Spring season anime is over and now Summer season anime are coming out. Here are the list of anime I've watched so far for Summer.
Overlord season 3 - Seeing last epi of season 2 plus next day announcement of season 3, I was so stoke! Season 3 epi 1 didn't fail me. They took Book 8 extra arc as epi 1, but it still made it good. I'm expecting war arc gonna be happening, so I can't wait!
Satsuriku no Tenshi - They try to make it scary. They brought famous voice casts... but I think, this series will flop.
Isekai Maou to Shoukan Shoujo no Dorei Majutsu - This series is mix of Overlord and Madan no Ou to Vanadis, but with more harem/fan service. Fan service is a bit too much, but I'm hoping to see story will be decent.
Hataraku Saibou - Want to know about your body and how it works in comedy form? This is it.

I enjoyed the epi 1 and they used white blood cell, red blood cell and other cells as an individual character. Overall it was fun to watch.
Island - This series reminded me of anime series We Without Wings plus small amount of ef: A Tale Memories. Not sure how this series gonna go.
Hanebado! - Japanese anime can make any sports into hardcore anime. This is a good example, this series is about playing badminton. I'll just leave it at that.
Hyakuren no Haou to Seiyaku no Valkyria - This series have same feel as Isekai wa Smartphone to Tomo ni. Main hero uses smartphone in the world that shouldn't have one... plus harem.
Shichisei no Subaru - This series is copy of AnoHana. Literally AnoHana that adapted to MMORPG. Almost same kind of charas are seen as AnoHana. So if you liked AnoHana and want a bit different world, this is the series to watch.
Chio-chan no Tsuugakuro - I was really surprised to see this series made it into anime. It's a funny manga without a doubt... funny part is this is first non-hentai manga manga-ka wrote. lol If you like funny slice of life, I highly recommend it.
Harukana Receive - I knew this day would come. The day that they gonna make beach volleyball. Not complaining one single bit here

Overall I do enjoy the art, but story... well let's say Haikyuu is better.
Asobi Asobase - Don't let the OP fool you. This is over the top slice of life. I had several WTF moment that made me laugh and some moment turn my head sideway. If you like Cromartie High School kinda joke slice of life anime, worth watching.
Jashin-chan Dropkick - Series just drop you at middle of manga expecting you to follow along without an issue... and it's fine. Cuz it's not very complicated series. IF you ever watched Nyaruko, it's pretty much that.
Gintama.: Shirogane no Tamashii-hen 2 - Damn them for making 2 different season for final arc of Gintama. Love Gintama series and sad that it's ending, but they sure know how to drag it out. Still love it
Angolmois - It's a story about war between Japan and Mongolia which happened sometime in 1200. Studio is NAZ, which is newer studio, but have made pretty action anime series, so I have high hope for this series.
I'm still waiting for AoT and need to watch few other series. Those review will be later on.
