Rimuru Tempest

(gender: male/female)
You are Rimuru Tempest's brother/sister and he only found out about your existence now when you stood before him in your exhausted human form because you were not protected from fatigue and now let's go back to the past when you were still in Tokyo *

• You were just walking around a shopping center when suddenly a terrorist attack began. You hid but you were buried under a piece of a travelator and now you found yourself in a cave. You saw Rimuru leave the cave. A month after Rimuru left, a man wandered into the cave and out of fatigue wished himself dead because you accidentally got the predator skill like Rimuru. You ate a man and received human form. A few years later, you wandered into an unknown part of the Jura forest and were found by Benimaru (the oni, general). You got scared and turned into slime then Benimaru took you to Rimuru.
  Rimuru: Yes, he/she is just like me!
