Summer Season 2021 Anime Worth Watching

Jul. 6, 2021

Summer hast cometh, and so the anime of the season has begun airing. Let’s dive into this seasons’ lineup and check what’s worth a watch and what will end up in the trash where it belongs.

Ratings and links to AniList are provided for each show.

Note: The post will be updated as more shows has aired and we’ve had time to watch and assess them. If a show isn’t listed, even after it’s aired, then either we just haven’t watch it yet, or it simply means your favorite show is shit and has no place here.

The Good Stuff

First we’re blasting off with the truly good stuff – what every anime fan needs to watch this season. If a show’s in this section, it’s a guaranteed must-watch.

Jahy-sama wa Kujikenai!

Jahy-sama wa Kujikenai! EP01

The anime of the millennia is finally here. I feel as if no matter what I say – how thick I lay on the praise – it would never be enough to describe how great The Great Jahy Will Not Be Defeated! is(*). Really, just go and grab yourself an episode on this. Rating: 10/10
*: Statement might be a (tiny little) bit over the top. Still, watch it, the show’s actually pretty dang great. In fact, read the manga, too; and if you can stomache letting the morons over at Sqeenix any money, consider buying the official translation. Or, better yet, buy the original from Rakuten or something.

Kobayashi-san Chi no Maidragon S

Kobayashi-san Chi no Maid Dragon S2 EP01

The second season of Maid Dragon is upon us, and so the world shall be watching it. And no, there’s no room for discussion here. Now, go out and watch Miss Kobayashi’s Dragon Maid S. Rating: 10/10

Tensei Shitara Slime Datta Ken S2

Tensei Shitara Slime Datta Ken S2 EP01

If you enjoyed the first season of Slime-boy, then you’ll probably like to have more of monstrously OP slimy and his cute harem of girls. If you didn’t enjoy the first season, well, there’s probably something wrong with your taste and you should be euthanized on the spot. No, but seriously, you’ll want to skip this one. But if you did like the first season, then you should go out and watch Tensei Shitara Slime Datta Ken 2nd Season. Rating: 8.5/10

Mahoutsukai no Yome: Nishi no Shounen to Seiran no Kishi

Mahou Tsukai no Yome: Nishi no Shounen to Seiran no Kishi - 01

This series is just fantastic. The parent series is a must-watch, and this OVA is simply great. If you haven’t already rushed to grab yourself the latest releases of this series, or if you’re unfamiliar with the series, then do yourself a favor and go check out The Ancient Magus’ Bride: The Boy from the West and the Knight of the Blue Storm. Rating: 9/10

Shiroi Suna no Aquatope

Shiroi Suna no Aquatope E01

While there’s little plot to go by this soon into the series, the premise and overall atmosphere is great. The art and animation is a delight to look at, and the characters are cute. Really, what more can you want from a nice and chill series. Hopefully it stays like this and doesn’t devolve into complete garbage drama bs. So, check out The Aquatope on White Sand if having some amount of baseline drama, coupled with fantastic visuals and sound direction seems like your kinda deal. Rating: 8/10

Bokutachi no Remake

Bokutachi no Remake EP01

Kicking off with a great style and animation, and an interesting premise, the first episode of Remake Our Life! has impressed. Well worth checking out. Rating: 8/10

On a sidenote, the English title is not accurate. ぼくたちのリメイク (bokutachi no remake) is literally Our Remake. What was wrong with that title? I see no point in changing it, other than for the sake of localization.

Seirei Gensouki

Seirei Gensouki EP01

Check out Seirei Gensouki: Spirit Chronicles is you’re into isekai, kemomimi, and all that good stuff. Rating: 8/10

Genjitsu Shugi Yuusha no Oukoku Saikenki

Genjitsu Shugi Yuusha no Oukoku Saikenki EP01

While I know from reading the light novels, the later episodes (if we get that far) will have the series tank a bit, this one should be a good ride for the moment. Watch How a Realist Hero Rebuilt the Kingdom if you like plenty of kingdom building, military strategy jargon, master strategists in action, and lots of nice waifus. Rating: 8/10

Kanojo mo Kanojo

Kanojo mo Kanojo EP01

Harem comedy anime(?) but with an actually fun type of humor. Watch Girlfriend, Girlfriend if you like harem, comedy, and ecchi. Rating: 9/10

Kaizoku Oujo EP01

Despite being a “ScrunchyRoll exclusive,” this anime has gotten off to a promising start. While it remains to see if it manages to keep being good, or if it ends up like everything else the likes of CR an Netdix touches, for now, Fena: Pirate Princess gets a strong recommendation if you like adventure, drama, and most of all, pirates. Rating: 9/10

Otome Game no Hametsu Flag shika Nai Akuyaku Reijou ni Tensei shiteshimatta… X

Otome Game no Hametsu Flag shika Nai Akuyaku Reijou ni Tensei shiteshimatta… X EP01

As if I could forget to put this series on the list. I really shouldn’t need to, as everyone should already have watched the first season, but just in case you haven’t: Go out and watch the first season, like it a lot, and then run off to grab all the latest episodes of this season and continue liking the hell out of this one. Grab yourself a copy of My Next Life as a Villainess: All Routes Lead to Doom! X (Hamefura S2) already! Rating: 8/10

Mahouka Koukou no Yuutousei

Mahouka Koukou no Yuutousei EP01

Yes, it’s this godforsaken series, you got a problem with that? No? Didn’t think so. But hey! If you do, go down in the comment section and screech at me how wrong I am. Nudge, nudge~ Anyway, watch The Honor at Magic High School if you liked the main series – The Irregular at Magic High School. Rating: 7/10

Again, one a sidenote, this series’ title is just bad grammar. Alternative, proper title: The Honor Student at Magic High School

Tantei wa Mou, Shindeiru.

Tantei wa Mou, Shindeiru. EP01

Contrary to its title, the Detective is, in fact, not already dead – not from the get-go anyway. This series has supernatural themes to it – something which really surprised – but might still be a good series. So, if dead detectives and supernatural hijackings should like something you’d appreciate, then you should watch The Detective Is Already Dead. Rating: 7/10

Peach Boy Riverside

Peach Boy Riverside EP04

Absolutely stupid name for a series aside – it does make you think it’s gonna be some hardcore gay swimming shit – this one seems alright. That said, remember to watch Peach Boy Riverside in airing order, as it’s being release out-of-order, with this first episode actually being episode 4. Wait until at least four episodes is out, then look up the proper watch order, but it’s borderline unwatchable like this. Rating: 7/10

Tsuki ga Michibiku Isekai Douchuu

Tsuki ga Michibiku Isekai Douchuu EP01

This one threads the edge of being relegated to Trash of the Season already, if only for the fact that they’ve somehow managed to completely fuck up the MC’s character setting. Still, the girls is cute, and the WN was pretty sweet, so TSUKIMICHI -Moonlit Fantasy- will remain here for the time being. Rating: 7/10

Cheat Kusushi no Slow Life: Isekai ni Tsukurou Drugstore

Cheat Kusushi no Slow Life - Isekai ni Tsukurou Drugstore EP01

Less than stellar animation, but Drug Store in Another World - The Slow Life of a Cheat Pharmacist could still be a nice and chill watch. Rating: 7/10

Honorable Mentions

Now on to the shows that seems less interesting, but might still be something to consider for those that are starved for yet more animated goodness.

Vanitas no Carte

Vanitas no Carte EP01

The light novel series is apparently pretty good, so the anime could well be great, but this first episode didn’t really impress. Still, check out The Case Study of Vanitas if vampires and decent animation, coupled with weird gay vibes sounds like something that’s up your alley. Rating: 6/10

Kageki Shoujo!!

Kageki Shoujo!! EP01

I’ve nothing particular to say about this one yet. It might get better, or it might be relegated to the Trash later on, but for now Kageki Shojo!! will be a Maybe on the to-watch list. Rating: 6/10


Re-Main EP01

Guy gets in a car accident and loses his memories of the past 3 years, then decides to (re)join the watersports club with his bros. Kinda gay, but might get better as the episodes comes out. Give Re-Main a watch if that sounds cool. Rating: 5/10

Megami-ryou no Ryoubo-kun

Megami-ryou no Ryoubo-kun. EP01

If you’re big on mindless fanservice, then Mother of the Goddess’ Dormitory might just be the perfect anime for you. Rating: 5/10

Uramichi Oniisan

Uramichi Oniisan EP01

So yeah, the novelty of the comedic “life lessons” of the bipolar Uramichi-san in Life Lessons with Uramichi Oniisan kinda wore off by the time the second episode aired. Still, for the right person, this show still might be of interest Rating: 5/10

Shinigami Bocchan to Kuro Maid

Shinigami Bocchan to Kuro Maid EP01

The series uses that horrid 3DCG garbage style we all know and hate, and the “Bocchan” (坊っちゃん) seems kinda daft, but at least the maid is pretty nice. For now The Duke of Death and His Maid will be a “maybe” to watch, but might get relegated to trash later on. Rating: 5/10

Trash of the Season

Here’s where the garbage dump of the season will get featured. Shows that were previously in “The Good Stuff” or “Honorable Mentions” might retroactively be relegated to this section if they turn out to be, in fact, trash.

100-man no Inochi no Ue ni Ore wa Tatteiru 2nd Season

100-man no Inochi no Ue ni Ore wa Tatte Iru E13

Straight in the Trash it goes. The first season were beyond terribad from start to finish, and going in line with its first twelve episodes, the second season has started off in just as an exceptionally lackluster fashion. With that said, unless your favorite pastime is touring sewer; having your testicles shaved with a rusty cheese grater, and then repeatedly smashed with a sledgehammer, you’re probably better off not watching I’m standing on 1,000,000 lives Season 2. Rating: 3/10

Deatte 5-byou de Battle

Deatte 5-byou de Battle EP01

Battle Royale – The Anime, so once again, straight into the Trash it goes. Unless your fetish is tearing out your eyes while getting showered with hydrofluoric acid, you’re better off skipping Battle Game in 5 Seconds. Rating: 2/10


D_Cide Traumerei The Animation EP01

Yet more low-effort 3DCG garbage. Welp, into the Trash it goes. Still, you might want to check out D_CIDE TRAUMEREI THE ANIMATION if the idea of performing eye surgery with a rusty fork sounds like something you’d enjoy. Rating: 3/10

Scarlet Nexus

Scarlet Nexus EP01

Unless you’re a fan of shitty story and horrid 3DCG animation, then you’re better off skipping this one. Still, if you’re desperate for something to watch, or just interested in watching the trash fire that is Scarlet Nexus, then have at it. Rating: 2/10
