Secret units are the rarest and mostly the strongest units in ARX, and with them, you'll be able to clear even the hardest content with ease. But getting secrets can be hard, especially if you don't know where each secret drops. So, to help you out, here is our complete guide on how to get every secret unit in Anime Rangers X!
How to Get Bunny in Anime Rangers X

Bunny is a new secret unit that came to Anime Rangers X with the Easter update. To get it, you'll need to complete the Easter Event stage, collect Eggs, buy Egg Capsules, and open them. Each time you open an Egg Capsule, you'll have a 0.1% chance of getting Bunny.
How to Get Fire Fist in Anime Rangers X

Fire Fist is by far the strongest secret unit in Anime Rangers X right now, and to get it, you'll need to stay in the AFK World (AFK Chamber). The chance of getting Fire Fist from the AFK World is 0.5% every 15 minutes. Because it's so RNG and the chance is so low, Fire Fist might be the hardest-to-obtain secret unit in ARX as of now.
How to Get Eclipse Sorcerer in Anime Rangers X

Eclipse Sorcerer is one of the two secret units in Anime Rangers X you can get by doing Ranger Stages. Eclipse Sorcerer drops with a 1% chance any time you complete one of the Leaf Village Ranger stages (Act 1 - Shadow's Awakening, Act 2 - Rising Storm, and Act 3 - Village Under Siege and each).
How to Get Solar Fist in Anime Rangers X

Solar Fist is another secret unit in Anime Rangers X that you can get by doing Ranger Stages. For Solar Fist, you'll have to do Green Planet Ranger Stages, and there is a 0.05% chance he drops on Act 1 - Invasion Begins, 0.1% chance on Act 2 - Galactic Chaos, and 1% chance on Act 3 - Emperor's Wrath.
How to Get Shadow Knight in Anime Rangers X

Shadow Knight is currently the only secret unit in Anime Rangers X that you can get from Summons. The chance to get Shadow Knight from both the Standard Banner and the Rate-Up Banner is still not listed in-game, but it seems to be around 0.1% for Standard Banner and 0.2% for Rate-Up.
How to Get Cursed Love in Anime Rangers X

Cursed Love is probably the second-hardest-to-obtain secret unit in Anime Rangers X right now, and to get him, you'll need to clear the Boss Event. The Boss Event stage is pretty hard, and you'll need good units for it. Also, there is a limited stock of 10,000 Cursed Loves, so if you don't hurry, you might not be able to obtain it later. The chance to get Cursed Love each time you complete the Boss Event is 0.1%.
