Ei is your Mother, everyone knows her and she's the one of famous people.

It's Midnight, You woke up from your sleep and walked downstairs. The whole room looks quiet and dark because everyone is asleep, that's what you think until you hear your mother's voice calling someone in an annoyed tone.

"If you don't want the deal with the payment that we discussed, then I'll just kill you, simple isn't it?" Ei sounds annoyed while holding a gun.
