I HAVE BEEN LOOKING FOR A SUPER GOOD MAGICAL GIRL GAME FOR SO LONG AND THIS IS IT!! It captures the main themes of a magical girl: Friendship, teamwork, strength, and embracing the person you are, while also still putting a unique stamp onto it! You can tell the people in this game love each other and that means so much to me. I also want to say it's such a delight to see a Magical Girl game written by people who clearly have watched and like Magical Girl series, bless y'all. I've been streaming this and it has been a BLAST to make theories about, and oh my GOSH does it feel good when you get a theory right. The narrative is very good at guiding you with sprinkle of information without being obvious, so this is also a very well-done mystery, too!! Absolute banger of a game so far, I hope more people see it.
lock & key is a bite-sized vn that gives you everything it says on the tin: magical girls pursuing a serial killer. as far as magical girl media goes this is very much post-madoka Dark Magical Girls (some of the bgm is extremely We Have Kajiura Yuki Style Tunes At Home, even), and if you're into magical girl anything chances are you already know how you feel about the post-madoka subgenre. what i enjoyed most about lock & key is that it comes at the genre from an unorthodox angle. you don't often get stories of mentorship from the mentor's perspective; there also aren't anywhere near enough stories out there about intergenerational wlw community building (Im Sure You Can Intuit Why). and with protagonists pushing 30 and the conflict of these older characters on the verge of aging out of their superpowers, the story necessarily incorporates a lot of thematic parallels to how a lot of teens and twentysomethings feel like everything fun in life is going to end and you'll stop being you once you've survived however many trips around the sun. what this transitioning point means for each of the adult characters, how they relate to their powers and their time as magical girls in a setting where magical girls are essentially child soldiers with the perks of cool costumes and superpowers, and how they interact with The Youths as older millennials vs young zoomers, is the emotional meat of the story here. imo it pairs well with the parallel queer community themes necessarily invoked by this being a yuri title. what does it mean to be a gay adult? how do your perspective and your priorities change, particularly if you're a pillar of community? other things: all the character designs are really good, particularly the magical girl costumes, which very much suit each character's personal vibe. it's always great to see the push of the past 15~20ish years for black magical girls bearing fruit, and additionally great to see a jewish character in the vn sphere at all, esp with the way there's clearly been research put into integrating sherri's culture & religion into her behavior--seeing her pray and such as a character trait as natural as the way christian characters will casually invoke jesus in everyday conversation. (though i do not think anyone actually says "oy vey" quite that much in real life lol.) if there's any point of constructive criticism i have to give, it's that i think the story could have stood to be a bit longer, particularly for the price point--lock & key took me about 3 hours* to collect all endings and achievements, compared to other recent studio elan releases at the same price or slightly higher, which tend to have double the word count at least. the characters and setting are definitely fun enough to merit a little more meat on this particular bone, i think! so, if you're having to keep your belt tight during these trying times tm, perhaps wishlist this one and wait to pounce until it's on sale...? it is definitely worth playing if you are going eyes emote at the description and themes, though. *vndb says average completion time is more like 4 hours, and this being a vn your playtime will depend on your reading speed.
Another solid entry from Studio Elan. Refreshing portrayal of a married lesbian couple and strong representation all around. The story was good too.
I really enjoyed Lock and Key as a fan of Studio Elan vns already. In terms of Studio Elan games I found it to be fairly more simple and short then most of their other offerings, but still lengthy enough to tell its story. One of the big things about this one I really liked was the main couple of Sherri and Kealey already being married. I loved every scene of them being romantic with each other, it's so nice seeing them have a stable relationship without any of that will they won't they/ /focus on tension in their relationship. As much as those things can be enjoyable, it was so refreshing to see the pure love of the two here, especially since it allows more focus on the plot threads of the murder and training of the next generation. The magical girl plot was really well done. I love seeing how the aging magical girls try to find their footing now that their magic is fading.I also find it a nice juxtaposition with Ruby trying to find her place as a magical girl. Without spoiling I do wish there was more time in the early segments just because I feel the reveal of the murderer came way too early. While I like how the rest of the game deals with the fallout, it really does not feel like a mystery when most of the game there really isn't one. That being said, the game is still overall really enjoyable story wise. This was one of the visual novels I found myself hooked on until it was over, and with its short run time it never outstays its welcome. My only real other complaint is I do think the game needs a longer epilogue, the good ending is nice but it definitely feels bare bones. This is especially the fact that we don’t even see Ruby at the end of the good ending, just a slight mention of her. It was kinda a bummer we don’t get a more in depth what happened after but still the journey was good. I loved the characters and the dynamics they carried. The themes of letting go of the past or being buried by it was really well done. I also really enjoyed how it portrayed the magical girl life, especially from the pov of 29 year olds about to hang it up for good. There was a good mix also of normal studio elan dialog and the more horror aspects that come from it being a story about murders. Definitely worth checking out.
There is not enough magical girl media with adult magical girls, so I really appreciate Lock & Key for filling in this niche! I would not entirely describe this as mystery, since the mystery component of the story is resolved pretty quickly, and even then I think the culprit is pretty obvious (though it might be just me). But I think it's pretty nice as a magical girl story, especially since it's not very typical due to featuring adult protagonists. Definitely recommended!
Another good title from Studio Élan, Heart of the Woods was one of my favorite titles I played in 2025, and I also liked Please Be Happy. Even though I'm not super fond of the Magical Girl genre, I still liked this title, just less so than the other two. The mystery premise is nice, and it's interesting that the "who" is solved pretty quickly, with the "why" becoming far more important. There are four endings, depending on how you act toward two different characters. One I'd consider a good ending, while the others are bittersweet to bad. I also like that your viewpoint characters are older and more mature than is typical for the genre, Overall I still preferred the characters in the other two Studio Élan titles I played more than this, Heart of the Woods did the flawed protagonist portrayal far better. [spoiler]The goddess isn't a very good judge of character for who it empowers as magical girls...[/spoiler] This one's a bit short, around 3 hours for all four endings and 99% dialogue obtained (I'm unsure where the last line is). While it doesn't support controllers, it played well on the SteamDeck with the default mouse and keyboard mapping.
There's a lot of directions a magical girl story can take, and Studio Élan certainly don't skimp on [i]Lock & Key[/i], delving into themes of growing up and losing out on the wonders of youth, all without being a stereotypical coming-of-age narrative. The characters are instantly likeable, the music's lovely, and the art and effects used particularly in the game's bigger moments do an admirable job of bringing you into the action. Unfortunately, the choice to regularly shift character perspectives without clearly telling the player whose mind they're now inhabiting means that the writing can occasionally be confusing, in my playthrough requiring me to frequently rewind and re-read certain passages. There are also points where the story either feels padded out or like it's shoehorning in scenes without consideration for how they look given the broader narrative context. And if you're looking for a game with deep, branching paths, this one isn't it, with your choices throughout the game only affecting how the final few moments play out. Despite this, I don't regret playing through [i]Lock & Key[/i], nor getting 100% in it. I wouldn't exactly call it light and breezy, but it might actually be the most accessible Studio Élan game I've played. It's a solid entry point to their writing and world-building; it's just a shame that — ironically — it's not quite as magical as some of their other offerings.

An enjoyable little story with multiple branching paths to take! It's not often you see a game featuring magical girls, let alone in a committed relationship. Loved reading it and seeing the mystery through. Gotta love that pink thing too!
If you play Lock & Key for what it is--a romantic suspense story starring married magical girls--it's perfectly fine. In some ways it's pretty refreshing; few romance stories in any medium, let alone games, focus on relationships that already exist, and I loved the relationship between Sherri and Kealey, plus how they interact with and mentor Ruby. I'm not actually a particular fan of magical girls, so I can't say whether it does the concept justice to a fan, but I liked the worldbuilding surrounding it and how it ties into the main plot. I picked "suspense" rather than "mystery" in my description of it for a reason; besides the player's lack of input, the culprit of the serial murders becomes [i]very[/i] obvious fairly soon after the beginning of the game, and it isn't long after that when the killer admits to the murders. There is still some investigation, but I would say that where the game shines is in building up tension. I liked Lock & Key, and I don't regret backing it on Kickstarter, but unfortunately it's pretty obvious that it was supposed to be a much bigger game than it ended up being. The biggest hint is in the in-game codex, which has its own separate section for all the cases you solve despite the fact that you only solve one case throughout the entirety of the game. I get the feeling that the game was supposed to focus a lot more on solving individual mysteries with the serial murder plot being a subthread that would have built up over time. But for whatever reason that didn't pan out, so in the game we [i]have[/i], there's a single mystery [spoiler]that more or less gets solved by itself without the player's input[/spoiler]. Outside of the story, the game also has some really good art and music, and a dynamic presentation that I liked a lot. The photo mode was an interesting addition I haven't really seen in visual novels before.
