Haruhi

Old af, but, The Irresponsible Tyler

Escaflowne - with modern animation and a full orchestra

Galaxy Express 999 & Captain Harlock

Vampire Hunter D

Big O

Two things pop into my mind at least.

1. Tokyo ghoul. I want a FMA brotherhood reboot. They would only need to do the second season really. (I know, very original)
2. Votoms. I just want this in some modern graphics. I feel like a reboot of this series could gain some popularity currently. Less “real robot” series more gritty military Real Robot

Another season of One-Punch Man.

I'd like to see Pumpkin Scissors and Zipang completed up to the ends of their respective manga (although Zipang was controversial enough that it might be really difficult to get it made). Likewise, Kamisama no Inai Nichiyoubi up to the end of the light novel series. And, just as an extra, it would be nice to see the last arc or two of Ghost Hunt make it to anime, although that would have to be an OAV as I'm pretty sure it would make six episodes max.

Akashic Records of Bastard Magic Instructor – i remember something big started to happen at the end of season, so i wish there was a second season. Also can mention: The Ones Within.

Serial Experiments Lain was weird enough I wouldn’t mind more.

Armitage

Somebody already mentioned it but Air Gear.

Read or Die…It had a series but I never got to watch it. I’ve only seen the OVA’s. So this is probably just a ‘I should watch that’…forgot about it.

Captain harlock

I need Hyouka S2.

Hmmm, a number of very weird ones come to mind first...

• Shangri-la (2009)
• The Third: Aoi Hitomi no Shoujo (2006)
• El Cazador de la Bruja (2007)
• Real Drive: Sennou Chousashitsu (2008)

Maybe because I had too much time to watch obscure stuff back then, and I love me some rare animus. Then again, they all weren't all that good, probably why they only had one season. And it's all female-led sci-fi I just noticed, shows my preferences...

Outlaw Star.

No game no life

Charlotte. Just a reboot would be cool to see or maybe same universe different characters.

Deadman wonderland

That one... With the city and the eyes... Fuck what was it? Blood blockade battlefront! I loved the setting and world building.

Ouran high school host club

I'm sorry everyone. I'm going to wish Berserk back again. Maybe next time it'll be good

Claymore

The Guyver

"K-On!" sequel pls 🥺

Also, "Gangsta." did not deserve what happened to it. Same for "So I'm a Spider so What?", although it's rather recent.

And why do all the titles that come to mind have freakin punctuation in them?

Gantz. I really love that idea of the dead world on the other side of our reality.

High-school of the Dead

No Game No Life

Tower of God (just rewrite the whole thing with the same premise)

Baccano! was really good, I wish it hadn't ended where it did

Ghost Stories. Specifically the dub.

Full Metal Panic. It’s one season away from being finished.

Golden Boy

Honestly, even though it's already a masterpiece, it would not hurt my feelings to see a reboot of Chobits.

Give me two new seasons with new art, maybe explore some more of the storyline or something.

Failing a reboot where they redo it with modern art techniques and everything, maybe there could be a parallel line, or pick up where it left off and give us one additional glorious season of Chi taking her rightful place as the persocom empress of the world or something.

Air gear

Deadman Wonderland. Likely a reboot more than a second season

Also a bonus; Ebichu. Please. More raunchy adult animated comedy anime please. What happened with that genre??

Space Brothers had the first 20 something volumes turned into a fantastic 99 episode anime, but in 2014, they caught up to the source material so stopped. It totally deserves a continuation, as there's another ~20 manga volumes out now.

Well, assuming that a modern remake or continuation can manage to recapture the magic of the original and retain its style:

Bubblegum Crisis (NOT Tokyo 2040)

What's considered "older" anime?

I'd love to see more G Gundam but it's hard to imagine them actually doing that. They released a new novel though so maybe...

I just want my HG Nether Gundam kit. Is that too much to ask?! Maybe a HG Cobra Gundam too, and a RG Nobell Gundam to match RG God Gundam?

Nana

NGNL.

My answer to this used to be Panty + Stocking, but they have a new season coming out on my birthday!

I guess now my pick is 009-1. I really love a good East vs West rivalry, and having a femme James Bond doing espionage in a world where the Soviets never collapsed really hit a lot of notes. I gets pretty weird towards the end, and I wish they had another season to go even weirder.

2020s

Needs a sequel

86 - still has source material to adapt

How heavy are the dumbbells you lift? - still has source material to adapt

Hyouka - still has source material to adapt

Needs a reboot / remake / sequel

Gundam: Witch from Mercury - could have been extended to show us more of its lore

2010s

Needs a sequel

Cautious Hero - still has source material to adapt

Sakura Trick - still has source material to adapt

Too Old

Needs a reboot / remake

Gundam X - deserves to be properly made instead of getting cut short due to pressures

Wait a second. Some of these anime came out only recently, you may say.

That just mean you are old, boomer. /s
