There are more than 100 cards to build a deck with in HoloSeeker, but if you pick Usada Pekora, you’ll also need to keep an eye on how many carrots you have.
Drawing cards generates Carrots, which can then be used to power some of her other abilities, so a good run can quickly turn into finding ways to draw more cards, make more Carrots, and then actually do something useful with the growing pile of vegetables you’ve accumulated.
And she’s only one of the characters.
Released in November 2025 by developer Imoyokan and publisher holo Indie, HoloSeeker is a Hololive deckbuilding roguelite RPG where each playable talent brings their own mechanics into a run. In April this year, the game hit 5,000 downloads. It currently has just 66 reviews on Steam, despite 89% of them being positive, which makes it surprisingly easy to have missed even if roguelike deckbuilders are usually your thing.
Everyone Has Their Own Way of Breaking a Deck
Pekora’s Carrots are only the start of what changes when you pick someone new. Nekomata Okayu has low defence but high evasion, making her much better at avoiding damage than taking it. Takanashi Kiara gets Phoenix Feathers that can bring her back after reaching zero HP, giving you a second chance when a fight goes badly.
Fuwamoco, meanwhile, wants to keep attacking. Repeated attacks build Mischief Stock, which can then be spent to use more expensive cards. That gives you a reason to keep smaller attacks coming while building towards something much bigger, rather than simply filling the deck with the most expensive cards you can find and hoping you get to play them.
Those differences mean swapping characters can change what you’re looking for during a run. A card that works nicely with Pekora’s Carrots might not be nearly as useful when you’re trying to keep Okayu out of harm’s way, while Kiara’s ability to come back from the dead gives you a little more freedom to take chances.
There Are Plenty of Cards to Build Around
Runs take place across branching adventure maps, letting you choose a route through battles, events, shops, and other encounters as you work towards the end. More than 100 cards can be found along the way, with plenty of Hololive artwork and references worked into their abilities. You’ll also collect HoloCoins, which can be spent in shops whenever the current deck needs a little help before the next fight.
Anyone familiar with roguelike deckbuilders will recognise most of that structure. You start with a small deck, add cards as you go, and try to find combinations that can carry the run further.
It’s the characters that give HoloSeeker something different to play with. Instead of learning one set of rules and then choosing between slightly different starting bonuses, you have character-specific resources and abilities to build around. Pekora wants Carrots. Kiara has her Phoenix Feathers. Fuwamoco is building Mischief Stock.
There’s quite a bit to learn before you even start worrying about what’s in the deck.
Pekora Can Show You Around for Free
There’s a free demo available too, although that arrived a few months after the full game. Released in February 2026, it lets you play as Pekora through the tutorial and Marine’s Sea Area, giving you a decent look at the card system and her Carrot mechanic before buying the full version.
The roster has grown since launch as well. Ouro Kronii and Ichijou Ririka have both been added as playable DLC characters, while several existing talents have received additional skins.
That makes the relatively small number of Steam reviews stand out even more. HoloSeeker has been out for almost a year, has continued receiving new content, and still sits at only 66 reviews at the time of writing.
You don’t need to know every Hololive reference to understand the deckbuilding underneath it either. Knowing the characters will obviously make the cards, artwork, and little references mean more, but the actual job is still putting together a deck that can survive whatever the next part of the map throws at you.
Although if you do start with Pekora, there’s one thing worth remembering…Never turn down the carrots.
