Evaluation
Taimanin Collection: Battle Arena launched on July 8, 2020 as a free-to-play gacha card collection game. The game is built around ongoing live service mechanics: multiple gacha pools (Standard, Premium, and Mileage Gacha), purchasable premium currency, daily login bonuses, and rotating content. The store description explicitly states "More cards and games scheduled to update!" and the game has received card additions and new mini-game modes multiple times since launch (July 2020, August 2020, November 2020, November 2021). Most recently, the developer performed server maintenance on March 11, 2026, confirming the game is still actively operated. This is a game designed to keep players returning indefinitely through daily play loops and card collection — there is no concept of a content "completion" date for a game structured this way.
Evidence
Server maintenance scheduled for March 11, 2026, confirming the game is still actively operated as of early 2026.
Game features multiple gacha pools with purchasable premium currency (Red Gems), daily login bonuses, and daily game point caps — a classic live service monetization structure. Store explicitly states 'More cards and games scheduled to update!'

About this game
Tokyo. The demonic city, plagued with the demons from the dark realms.
The ancient rule has prohibited the demons from interfering with humans,
but with the humanity's dark descent, the pact is now history,
and the treacherous syndicates weave crime and chaos throughout the world.
In order to protect the nation, the Japanese government has established a special force,
consisted of ninjas who, with their might and skills, can fight against the demonic invasion.
The world will know them... as the Taimanins.
In Taimanin Collection, you can collect gorgeous beauties introduced in Taimanin Asagi: Battle Arena since 2014.
