Star Rail Chat Group, But Why Are the Group Members IF Routes?

Jing Tian, known as the “First Breakpoint King of Changle Heaven,” becomes bound to a parallel-world chat group system.

Emperor Three—Big Black Tower: “Kill kill kill kill kill kill kill kill kill kill kill kill kill kill kill...”

Titania II—Firefly: “Come join Super Glamoth and fight the swarm with me!”

Pure Knight—Robin: “Defend the beauty of the galaxy!”

Fan Artist—Hidene: “Even though I’m very useless, seeing everyone else so useful makes me really happy.”

Ranger—March 7th: “Damn it, I’ll strip your headgear right off!”

Yipin General—Qingque: “Old Jing, I want to play cards.”

Jing Tian discovers... his chat group members seem a little strange.

What do you mean all of his group members are from if lines!?
