Trinity Seven
Oshimeter
Synopsis
One morning, Arata Kasuga opens his eyes to find his entire town destroyed and everyone he knows gone, including his cousin Hijiri. The kicker? He didn't even notice, because a magical grimoire Hijiri left him rebuilt his reality as an illusion. When a mage named Lilith Asami shows up and shatters the fake world, Arata gets a choice: lose his memories or enroll in a secret magic academy to find the truth. He picks the academy, obviously. There he meets the Trinity Seven, seven elite female mages, each tied to one of the seven deadly sins, and starts learning to control powers he didn't know he had. The magic system here is actually pretty cool and more thought-out than you'd expect from a 12-episode TV series, with each sin corresponding to a different school of magic. What makes this one work is Arata himself. Unlike most harem protagonists who stumble around blushing, this guy is self-aware, flirty, and genuinely funny. He leans into the absurdity instead of running from it, which keeps the comedic and romantic moments from feeling stale. The action scenes hold up well too, especially once the stakes around Hijiri and the Breakdown Phenomenon start escalating. If you liked High School DxD's energy but wanted a slightly tighter magic system, or if The Asterisk War left you wanting a protagonist with more personality, Trinity Seven is worth your time. It's light, it's fun, and it doesn't pretend to be something it's not.

I thought the finale would go all-out nonstop, but I liked how it balanced flashy fights with quieter character moments. The animation stayed solid, the soundtrack gave the big scenes extra weight, and it wrapped things up while leaving me curious for more. Must watch.
Wow! Very intense episode right from the start. I was locked in watching Levi carry the pressure while everything else spiraled around her. The fast action, slick animation, and intense soundtrack kept me engaged the whole time. Really, a must watch episode before the finale.
Awesome episode—from one transformation to another! I loved the visuals for both Satan and Astral. We also got a bit of a twist that builds even more anticipation for what's to come. There was a lot of information to take in, along with some great character power development. You really need to watch this episode—there's so much more to come!
For me, this was another dialogue-heavy episode mixed with a few brief but intense scenes. I think the pacing is well balanced, and the soundtrack fits perfectly. We also got an awesome cliffhanger—I can't wait for the next episode!
This episode slowed down a bit. It was dialogue-heavy, focusing more on the lore, character development, and character dynamics. But then again, Arata is still Arata—you know what I mean if you've watched the previous episodes. That last part, though...kinda make me excited.
This was quite an emotional episode for me. As far as the power system goes, it just keeps getting broader and broader. We still can't get away from Arata's silliness, but maybe that's just how he is, haha. Overall, I'd say it's worth watching. Plus, I have a feeling something bad is about to happen soon.
Pretty intense episode—a great continuation of the previous one. I didn't think Levi could step up like that; she really held her own. We also got a sneak peek at the Headmaster's capabilities. I'd say this is a must-watch episode so far.
A build-up episode, I'd say. It introduced another member of the Trinity Seven. Although it felt slower than the previous episodes, it was still crucial to the plot, I guess. The character dynamics became even more interesting, and the power system got even more complicated this time.
Solid episode for me—it had some quick action scenes. Once again, the series keeps up its fast pacing and stays consistent with that stuff... but I won't mention it this time, haha. This series is really interesting. The power system is becoming even more complicated, but that's part of what makes it great.
This is really weird, I think. It's kinda like a filler episode, but it isn't. There was more explanation about magic, and it's still consistent with the pervy stuff, haha. But don't get me wrong—the graphics and animation are great. I don't know, I kind of liked it.
Oh my, what the heck? 😂 Interesting episode, indeed. It was a mix of silliness—or should I say perviness?—and serious world-building centered around grimoires and themas. Overall, it was a great episode.
To be honest, I didn't expect this right off the bat. 😂 Hilarious! Sure, the pacing was fast, introducing a lot of characters all at once with little to no explanation of what was happening, but it was still great. Solid first episode—I'm digging it.
A balance of hand-to-hand and magic projectile action! Not too bad, if I do say so myself. This episode really felt like a good finale. It literally splits the episode in half. The first half wraps up the action, and the other half is all about resolution and emotional moments, a solid watch overall! A nice, light show to accompany your weekend.
This is what I love about a show full of magic users: you really appreciate a character who doesn't use magic.. or rather, uses it in conjunction with hand-to-hand, physical melee attacks. You get beautifully choreographed fights instead of just two people throwing fireballs at each other. I also have to mention the soundtrack in this episode; while it's no masterpiece, it works well enough to carry the momentum of tense moments forward as we get closer to the finale.
Things escalate right from the very first second.... wow just wow! Arata's form took on a drastic appearance here and it looked incredibly badass, without a doubt! I also have to say that I really love this show's Archive and Thema aspects, they give each character a unique twist instead of just being more fanservice material lmao..
Starts off with a bang! It went straight into the thick of battle~~ the rivalry between Astil and Iliad was so cool to see. I would especially like to name Mira Yamana as the MVP for most adorable girl in this episode😭😍🥰. It was so funny to see her being completely vunerable with Arata without her magic.
This episode leans more into a slow burn at the start. It explains more about the lore for the sake of worldbuilding, with plenty of goofy interactions and fanservice thrown in here and there. Things escalate towards the end, though, so stay tuned until the end🔥🔥
Pretty entertaining episode overall, lighter tone but still moving the story forward. Some moments made the actions they did sound more ridiculous in a fun, harem way. As good as this episode may sound, it does stretch some scenes to an extent where it seems too long in my opinion~
This one felt more intense than previous episodes. There were some twists in the plot, and I love how the soundtrack did a good job building momentum. The fight choreography was pretty satisfying too. Definitely a 4.5/5 episode!
Nice balance of action and downtime here. The power system gets expanded a bit, and some scenes actually looked better than I expected. Rather slow-paced compared to previous episodes, but it still gives further worldbuilding material that may keep you as hooked as I am watching it!
