Monmusu Girls: Autobattler

Gotta Gacha’m all.

Developed by Meowspirit, Monsmuso Girls: Autobattler is exactly what you think it is, an Autobattler decked out in several layers of fan service, with a colorful and vibrant bunch of waifu ladies ready to conquer the minions of the resurrected Demon King. It's cheeky, grindy, and relies on the same mechanics the genre has seen a billion times before. It doesn't bring anything new to the table, but it confidently does its job as a standard mobile experience, providing enough fun without needing to spend anything at all. 

Autobattlers usually get a bad rap about how much of the game is being played for you. However, I strongly disagree with that perspective because it requires you to play strategically by ensuring your team is built correctly and that you've leveled and equipped them for the fight at hand. Yes, the characters fight on their own, but they need guidance, which is where you come in.

While you'll pick a protagonist, you have over forty girls to unlock via gacha mechanics and add to your team. You'll take on hundreds of battles, various challenges, dungeons, and arena battles to level up your team of eight girls, and ensure their equipment doesn't cause them to fall in battle. You'll do this by opening countless gacha chests and using currency and other weapons to forge the gear you have. It's a grind we've seen before in thousands of other mobile games.

Like most games in the genre, the story is built around a collective of characters all joining forces to stop a great evil. In this case, it is against the Demon King. You find a villager who has been transformed into a monster-girl at the start of the game, and team up with a fortune-teller who can see this girl’s destiny, and joins forces with you to see the path ahead. You'll encounter numerous foes that look to prevent this expedition, and countless challenges that are in your way.

The story itself is pretty light-hearted with plenty of cheeky and funny moments, as well as a huge cast of allies and villains that are peppered in to build out this story. Its narrative is detailed through visual novel conversations with impeccable artwork, and if you can find it, there is a patch that restores the original outfits to many of the ladies present, as the current version has a light bit of censorship.

When it comes to progression, especially for earning currencies and other items, it’s a shame you cannot repeat previous battles to grind away. This is where other modes come into play that I’ll talk about later. Each level you enter into will tell you what you are about to fight, what level your enemies are, and the expected power level of the baddies as well. That said, level 3-49 is where the game’s difficulty ramped up so hard that while 3-48 was a breeze, I was trounced on the next level with no chance to win. This is where other avenues of content were needed to be explored, having me sideline the campaign for a few hours.  

When it comes to mobile games in general, you usually have the same sort of menus and options that fill out the free-to-play market without countless ways to sneak a few bucks out of you. Monmusu Girls has a ton of monetization here across almost every facet of this game. There are Privilege Memberships that offer up bonus rewards, Weekly Hero stamp cards, a series of Gift Boxes, as well as Daily Packs, all on just one side of the screen. There is a Relay Pack that has a ton of items, but you have to buy items after every two free ones. This chest icon also features a few characters you can outright purchase in case the RNG gods are not paying attention to you. This chest also has countless paid options for items when your crystals run out.  

Now, all that said, you unlock a large number of items and girls just by playing through the story and through all the other avenues of content. There is also a challenge ticker in the top right that grants you items for completing quests, fishing, and more, at least when it doesn’t glitch out, forcing a reboot. Sure, boosting with various paid items will make it easier and open up more opportunities, but I never found the urge to buy a single item. Saying that, however, I was granted a small collection of items that granted me several flavors of currency to spend as well as enough gatcha boxes to unlock a series of girls, two of which I have in my team right now. 

Equipping items plays a huge part in boosting their power. Sure, you'll level up via gold and other factors, but you'll soon have an overabundance of gear. From weapons to armor and various other equippable items, you'll use other currencies to level them up in bulk, or use excess weapons to feed into them. You'll earn crystals that can be used to summon more girls, or at least fragments of them, as well as weapons and armor. These are earned fairly quickly by completing a ton of daily and weekly challenges, but the shop makes sure you know you can buy more. 

Each girl will also have what is called a Potential Breakthrough. This is how you essentially evolve them past the limitations of their current level. You’ll earn this via character shards are appear in the gacha chests. The boosts they get are significantly greater than that of just leveling. There is also a tab for outfits, but I never unlocked a single one, so I am unsure on how to procure these. 

Apart from the story campaign, you’ll have a series of expeditions to take on as well, each of which is unlocked at specific levels. There is an arena to test your teams against other players’ combinations, dungeon adventures via the Abyssal Ascent, a minesweeper-inspired option in Maze Exploration, to what feels like a whole second campaign in the Chaos Realm, where you choose from various options to tailor a set team with various traits as you progress. This is likely the most fleshed-out alternative to the campaign. There are also Daily Challenges, Hero Trials, and Joint Trials to take on as well. 

Visually, Monmusu Girls: Autobattler is very bright, colorful, and vibrant with some great artwork. While a few of the girls' artwork doesn't initially match the character portraits you see in conversations, the game certainly has a leg up on the competition via its fantastic artwork. The chibi versions of the girls in battle are fun, and you can speed up the battles to see the action increase in its chaotic charm.

Monmusu Girls: Autobattler can be a few good hours of fun, but eventually, the game does start to show its grindy reality that brings a lot of the progression to a halt. Regardless, it is something I'll continue to play, at least in my spare time. It has the charm and personality that many games of its ilk fail to offer, especially with a certain patch you can find to restore the game’s original vision. It can be repetitive and shove its bosom of currencies in your face, but that has been the mobile approach for years, so it at least provides options to keep the fun going.
