Arknights, I'm going to beat Kal'tsit, really?

You are a time traveler.
Good news: I've been transported to Terra, a land teeming with animal friends.
Excellent! As the Doctor of Rhodes Island, I will surely save this land from suffering. As for my leisure time, I can also chat about things like having four girlfriends outside of work or being number one on the vanilla betting list.
What do you mean by "I am Priscilla's dog"?
Ama-9, the predecessor to Ama-10, is, in terms of kinship, my brother Kal'tsit.
And now, my assigned task is to help Prisus achieve the Originium Project?
King against king, general against general.
Precys vs. Doctor, Hilda vs. Amiya.
So my task is to go and get Kal'tsit?
