There is no romantic pairing. The Trail Blazers have relatively little screen time. The main character is Conan (initially disguised as Ong Faros, and later others are introduced). He is considered to be on the gray side, and may have more contact with the red side.

It doesn't feel like it's either male-oriented or female-oriented; it's more like a human-oriented genre.

You are a pioneer. One day, someone claiming to be a system sends you to a planet in another world to find the hidden core of the planet and destroy it.

You: ? ? Are there also Great Lords of Annihilation in other worlds?

System: There shouldn't be any, it's not important.

You: ?! This is important, isn't it?!

Never mind, as a pioneering spirited trailblazer, you gladly accepted the task and embarked on a journey of role-playing as a character in Honkai Impact 3rd, creating a series of strange organizations.

Onpharos (faction):

The legendary detective of the First Investigation Division – Wan Di (Madmore)

The cat thief who steals jewels from Kid – Seiferia

Aglaia, the "Golden Weave" lady from the tailor shop

…

Regardless of the order of appearance, there is a rescue plot.
