Killstreak is a brand new Mythical unit in Anime Adventures, who draws inspiration from the Sakamoto Days character Gaku. You can get them from the Assassin Banner and evolve them into Killstreak (Speedrun).
Anime Adventures Killstreak Guide
Let’s take a look at how to get Killstreak in Anime Adventures. We’ll also take a look at how to evolve them.

How to Get Killstreak in the Assassin Banner
To get Killstreak, you need to summon them from the Assassin Banner. This involves participating in Assassination Contracts to earn Assassin Tokens in order to pull on the new Assassin Banner. That’s a lot of Assassins.
You need ten Assassin Tokens for a single pull and you have a mere 0.5% chance to pull a Mythic. Fortunately, only three Mythics are available in the banner and one of which is Killstreak. So, if you do pull a Mythic you have a 33% chance of it being Killstreak.
However, there’s a secret weapon: Mythic Pity. This guarantees you a Mythic character once you’ve pulled 200 times on the banner. That’s going to cost you 2,000 Assassin Contracts.
Better still, once you have maxed out your pity and pulled a Mythical, your pity resets. So, to get Killstreak, just keep earning Assassin Tokens, pulling on the banner, and getting a Mythical via pity.
This shouldn’t take you too long provided you can take on the higher tier Assassin Contracts. We’ve seen rewards range from a mere four Tokens to 375.
How to Evolve Killstreak in Anime Adventures
To evolve Killstreak, you first have to fulfil the requirement of 7,500 takedowns.
Then, head to the evolve area of the lobby, ensure you have the crafting requirements, then evolve the character into its Speedrun variant.
