Hundred
- Martial arts action
- Alien contact
- Light-hearted
Hundred is a 2016 action-romance anime about students wielding mystical weapons to fight alien invaders. It's a brisk, colorful school-battle series with romantic subplot chaos and character-driven combat. If you enjoy watching capable teenagers clash and flirt in equal measure, this hits that specific sweet spot between shounen earnestness and harem comedy.
Should you watch it?
Watch it if you want a school-set action romp where a fight is also a flirtation, and you enjoy the comedy of a hero who keeps getting dragged into a rival's orbit.
Skip it if you want a slow-building story with real stakes, since this moves briskly and leans on teasing banter more than on the mystery it sets up.
What it asks of you: Twelve episodes of about twenty-five minutes each, so it is a light commitment, and it wants you to keep up with a lot of rapid fights and rapid-fire jokes.

If you liked this
Gakusen Toshi Asterisk2015
Nearly identical premise—students at a floating academy train with magical weapons to fight invaders—but with slightly more polish and a deeper ensemble cast. Same energy, better execution.
But If you've seen Hundred, you've essentially seen this already. The novelty wears off fast when the setup is this familiar.

Rakudai Kishi no Cavalry2015
A classmate-rivals-to-lovers romance wrapped around spectacular one-on-one duels. The combat feels genuinely personal and the relationship development has actual weight and progression.
But More serious tone than Hundred; less wacky harem chaos if that's what you're after. Slower pacing in the middle third.

Date a Live2013
Same mix of action and romantic comedy chaos, but trading school battles for supernatural dating scenarios. Same spirit of 'manage multiple girls while saving the world.' Genuinely funny.
But The premise is absurd in ways that'll grate if you prefer grounded storytelling. Some fan service moments won't land if you're not in on the joke.

The wildcard
Something you would not have found on your own.
Kill la Kill2013
Both strip school-battle anime down to emotional core and rebuild it. Where Hundred plays the format straight, Kill la Kill interrogates why we watch it at all—but with equal affection for the material.
Transforms the school-battle formula into absurdist satire. Every trope Hundred plays straight—uniforms as power-up, harem dynamics, underdog hero—gets weaponized for commentary. Visually audacious in ways most anime aren't. The action is pure kinetic joy.
But Chaotic and aggressively weird. If you want coherent plot or realistic character arcs, this discards both gleefully. The fanservice is intentional and unapologetic; some viewers find it exhausting rather than funny.

More like this (7)
Saijaku Muhai no Bahamut2016
Magic swords, flying battleship school, protagonist with a dark past. Hits many of the same beats as Hundred but with stronger world-building and a more cohesive narrative through-line.
But More generic in tone. Lacks the particular charm of Hundred's character interactions and romantic awkwardness.

Freezing2011
All-girls military academy fighting alien invaders with powered suits. The action is kinetic and inventive; the bond between protagonist and his partner deepens genuinely across episodes.
But Far more fanservice-heavy than Hundred, to the point where it sometimes overshadows the plot. Violence toward female characters can feel gratuitous.

Absolute Duo2015
Academy of weapon-wielders where students pair up to fight monsters. Earnest tone, solid cast chemistry, and the partnership dynamic gives it slightly more depth than the premise suggests.
But Doesn't quite stick the landing. Final episodes feel rushed and the ending is unsatisfying. Less polished overall.

Seraph of the End: Vampire Reign2015
Military school training orphans to fight vampires. Darker mythology, more elaborate action sequences, and genuine stakes make it feel weightier than typical academy battle shows.
But Tonal whiplash between school comedy and apocalyptic war. The plot threads don't always cohere, and later seasons complicate rather than clarify.

Trinity Seven: 7-nin no Masho Tsukai2014
School of magic users with incompetent protagonist and a harem of smarter girls. Lighter and sillier than Hundred; genuinely good at comedic timing and character banter.
But Plot is nearly nonexistent. If you need actual narrative momentum or stakes, this will feel like spinning wheels. Extremely fanservice-forward.

Carole & Tuesday2019
Both find their heart in the connection between the protagonist and a girl who somehow 'knows him well.' Carole & Tuesday scales that intimate dynamic across an entire series, making friendship the real battle.
Two girls in space discovering music together. Completely different genre, but same emotional DNA: young women finding their strength through partnership, original-sounding soundtrack, gorgeous animation. Surprisingly moving without being sentimental.
But No action sequences whatsoever. Slow-burn character study disguised as slice-of-life. If you need combat or high stakes, this will feel slight and drifting.

A Certain Scientific Railgun2009
Both center martial prowess at a school, but Railgun flips the gender script and grounds its action in systems rather than raw talent. Different approach to the same engine.
Academy for psychic students in a sprawling city. Better action choreography, smarter world-building, and a female protagonist who outthinks and outfights everyone. The tone balances humor and genuine danger without tipping into either extreme.
But Franchise lore gets complex; watching in isolation works, but you'll sense depths you're not getting. Early episodes are slower than you might want before the larger mythology reveals itself.
