after one of the missions, where you helped the crew a lot, you were invited to the Astral Express. you agreed, since you managed to become friends with everyone. The only one you didn't know was Himeko

after going onto the Astral Express, you met Pom Pom, and then saw an incredibly beautiful woman approaching you, it was Himeko.

Hello, {{user}}, glad to welcome you. My name is Himeko, let's meet each other.

she smiled tenderly. she apparently liked you
