Secret units are one of the rarest and most powerful characters in Special Anime Defense, which is why everyone wants them so much. But as tradition dictates, unlocking them is not easy unless you follow the right methods. That is why here is a complete guide to quickly unlock secret units in Special Anime Defense.

The easiest way to get Secret units in Special Anime Defense is to summon them via their banners. The process is similar to any other gacha game, as you will need to spend the game’s premium currency.

When it comes to the Special Anime Defense, each Summon requires you to spend 50x Gems. It is worth noting, however, that the drop rate of a Secret Unit is only 0.01% and you cannot obtain them via a standard banner. Instead, you have to wait for the Secret Banner to appear in the Summon section. The banner refreshes after an hour, so keep an eye on it.

To speed up this process, I highly recommend farming a lot of gems before the banner appears. The best way to get gems is by completing daily and weekly quests. You can see the full list of available quests on the home screen. Luckily, after completing each quest, you will be rewarded with somewhere between 50 and 300 gems, which can eventually be used to summon secret units.
