The game features an expanding roster of characters from the Kaiju No. 8 manga, including all major members of the Defense Force and key figures from the series. You'll find characters like Kafka Hibino (in both human and kaiju forms), Mina Ashiro, Kikoru Shinomiya, Soshiro Hoshina, and many others, each with unique abilities and roles.

Characters come in different rarities (4-star and 5-star), with higher rarity units having stronger base stats and more powerful skills. The roster continues to expand with regular updates adding new characters and alternate versions of existing ones. You can browse the full list of characters on the Characters page.

To find out which characters are worth investing in, check our regularly updated Tier List, which ranks all units based on their performance across different game modes.

Character progression in Kaiju No. 8 The Game is multi-layered and requires investing in several areas:

• Leveling — Characters gain experience from battles and can be leveled up using materials farmed from various game modes, particularly Expedition Mode.
• Limit Breaking — Once a character reaches max level, you can break through the level cap using duplicate character shards or universal materials. Higher limit breaks unlock new skill tiers.
• Skills — Each character has unique active and passive skills that can be upgraded with specialized materials. Higher skill levels significantly improve damage and utility.
• Weapons — Each character can equip a weapon that provides stat bonuses and additional effects. Weapons can be upgraded with duplicates to increase their power.
• Uniparts — Equipment pieces that provide stat boosts and set bonuses. Choosing the right unipart sets is crucial for optimizing your character's performance.

Resource management is key — focus on building a core team first before spreading resources too thin. The Tier List can help you prioritize which characters deserve your investment.

The game uses a banner-based gacha system to acquire new characters and weapons. Players spend in-game currency — which can be earned through gameplay or purchased — on either character summon banners or equipment banners.

Key elements of the gacha system:

• Rate-Up Banners — Featured characters and weapons have increased pull rates during their limited-time banners.
• Standard Banner — A permanent banner with a fixed pool of characters and weapons available at all times.
• Pity System — A guaranteed SSR (highest rarity) pull after a certain number of summons, with the counter carrying over between same-type banners.
• Spark / Hard Pity — After a set number of pulls on a rate-up banner, you can directly exchange tokens for the featured character or weapon.
• Dupes — Pulling duplicate characters grants shards used for limit breaking, making dupes valuable for strengthening your roster.

Save your currency for rate-up banners of characters you really need rather than pulling on the standard banner. Check the Characters page to plan your pulls and see which characters are worth aiming for.

Yes, Kaiju No. 8 The Game is designed to be very accessible for free-to-play players. While there are optional purchases available — mainly cosmetics, convenience bundles, and paid currency — none of them are required to experience all the content the game has to offer.

As a free player you can:

• Progress through the entire main story campaign without spending.
• Earn a steady income of premium currency through daily missions, events, and game modes like Expedition.
• Obtain strong characters through the gacha system using free currency and the pity system.
• Compete in all PvE modes — Fierce Battle Arena, Total War, Large Conquest — purely based on roster development.

The key to success as a free player is smart resource management: save your currency for high-value banners, focus your upgrade materials on a core team, and use the Tier List to identify the best characters worth investing in. Spending money mainly accelerates progression by giving more pulls and materials, but careful planning can achieve similar results over time.
