Gacha is playing with me I swear

I need a cool Kanon and Hagumi.

I get a 4* Kanon. It's powerful. I now have a powerful, a happy and pure Kanon.

I get a 4* Hagumi. It's happy. I now have a happy, a powerful and a pure Hagumi.

I need a pure Arisa.

I get a 4* Arisa. It's happy. I now have a powerful, a pure and a cool Arisa.

Please send me your luck, I don't know how you guys do this...
