If you commit seppuku (honorable suicide), you want a kaishakunin. Since disembowling yourself is very painful, the kaishakunin takes your head off after you've made the fatal cut.
At that age, they can become tame. I could turn that one into a lap cat. I have a lot of experience with cats, and if you know how to treat them, even ferals can become quite sweet.
You joined the wrong raid!
I think you didn't wait for the invite to come in. If you want, we can try again around 8:10 (50minutes from now)

That was a darkrai. It's a really powerful 'mon. You need at least 4 high level trainers to take it down.
Another one hatches in about an hour, but that's probably too late for you.
