Lost Sword

Review by eFreeware

Lost Sword mixes action with flirting, wrapped around an anime fantasy story. You follow a group hunting the vanished holy sword Excalibur, and the game leans as hard on the personalities of that group as it does on the fighting. That combination, rather than any single battle system, is what sets it apart from the crowd of anime role-playing games on Android.

It comes from Wemade Connect, costs nothing to install and is rated for teens. The story starts from a familiar Arthurian frame: Uther Pendragon is struck down by the False King Vortigern, his daughter Elizabeth goes looking for Excalibur and disappears, and the scramble for the throne follows. From there it turns into an otherworld journey with a small named cast.

I would point this at players who like collecting and growing characters while a story unfolds around them, and who are happy to let battles largely run themselves. If you want to steer every swing yourself, the idle framing here is the wrong shape for that. If you enjoy anime art, voiced scenes and steady account growth, the mix looks well judged.

Idle battles with an anime face

The core of the game is a 2D side-scrolling battlefield where your party fights in real time while you watch, manage and grow. The developer describes it as an afk role-playing game, meaning progress continues through endless battles rather than demanding constant input. Your attention goes into who is in the party and how they develop, not into tapping attack buttons.

What gives those battles their character is the presentation. Characters are drawn as high-quality 2D anime illustrations and animated with detailed motions, and skills fire off as cutscenes rather than quick flashes. The developer bills these as feeling like real animation, and that is the part of the pitch I find most convincing, because idle games live or die on whether watching them is pleasant.

Voicing is the other pillar. A cast of voice actors performs the characters, and the developer promises that these performances deepen the experience. For a game built around liking its cast, voice work does a lot of the lifting, and it is the detail that would decide whether the flirting half of the concept lands for you.

The cast you travel with

The named characters carry the adventure. Morgana is the fairy queen who has gone into seclusion after repeated rebirths, Elizabeth is the missing princess whose gentle manner hides a determined streak, and Bedivere is one of Britannia's knights, loyal to Elizabeth and quick to tears. Ethan joins the search for the holy sword alongside them.

That is a small, deliberately drawn group rather than a faceless roster, and the game is built around spending time with them. The romantic thread runs alongside the fighting rather than replacing it, so the two sides of the game sit together rather than one crowding out the other. If character chemistry is what keeps you in a role-playing game, this is the hook to weigh.

Dungeons, raids and steady growth

Beyond the endless battles, there are dungeons to work through, a single raid, and event dungeons that rotate in with updates. Growth comes from clearing this content and building the party up over time, which is the standard shape for the genre and gives the idle loop somewhere to point.

The game has been updated since launch, with new content, a new event dungeon and bug fixes in the most recent patch. That rhythm matters for a game like this, because event dungeons are what break up the repetition of an endless battle loop. It launched on July 8, 2025, so the content base is still being built out rather than settled.

The scale is already there: more than a million installs and a 4.3 average from a large body of ratings. Those numbers tell you the game has found an audience, though they say nothing about whether its style suits you.

What it costs and what it asks of your phone

Lost Sword is free to download and carries no ads, but it does offer in-app purchases. That is the whole of the monetization picture I can give you: no advertising interruptions, and optional spending available inside the game. How far the free experience stretches is something you would judge for yourself once you are in.

On the hardware side, the developer sets a floor of Android 6.0, a Samsung Galaxy S9 or better, and 4GB of RAM. That is a modest bar by current standards, but it is a real one, and an older budget device may struggle. The game also asks for two optional permissions, one for connecting wireless devices such as earphones over Bluetooth and one for sending service notifications. Declining either does not affect gameplay.

There is an official community presence across Discord, Reddit, X, Facebook, YouTube and TikTok, plus a brand webpage. If you like following patch notes and event schedules, that is where the announcements live.

Who the action-and-flirting mix suits

This is for players who want an anime fantasy role-playing game they can keep running in the background while the story and the roster do the entertaining. The side-scrolling idle format means you can check in, adjust your party, watch a skill cutscene or two and move on.

It also suits anyone drawn to character-driven games where the appeal is the group you travel with, voiced and illustrated rather than implied. The romantic angle is a feature here, not a side note, so a player who wants pure combat and nothing else will find the tone doing something they did not ask for.

The teen rating fits that tone. This is a fantasy adventure with flirting in it, not a grim or explicit story, and the presentation aims at a broad anime-loving audience.

A free idle RPG worth trying if the cast hooks you

Lost Sword is a free, ad-free anime role-playing game built around idle battles, a named cast and a search for Excalibur. Its strongest card is presentation: 2D anime art, animated skill cutscenes and voiced characters, all wrapped around a loop that keeps running while you are elsewhere. The weaker side is that the loop is the loop, and the fighting largely plays itself.

I would suggest it to players who enjoy collecting and growing characters, like a romantic thread in their fantasy stories, and are comfortable with a game that progresses while they watch. Those who want direct control over every battle, or who find the flirting framing off-putting, will get less from it. It costs nothing to find out which group you are in, and the install base and rating suggest plenty of people have already made that call.
