I Have a Big Gift Crab in Honkai: Star Rail

My name is Liu Xi. I transmigrated to Jarilo-VI and got a crab. It's called "Holy Crab" and randomly gives me "gifts" from other worldlines every day. The first gift was Himeko Murata, on the brink of death and from the Honkai world. The second was a cat-ear headband. Once I put it on, my agility maxed out, and I even grew real, fluffy cat ears. ...Hey, wait, Crab Bro, did you steal Cocolia's Stellaron?! [Reader advisory: There is no romance for the protagonist in Volume One. If you want romance, it's only in Volume Two.] If you're going to start cursing in Volume One and say I'm forcing a couple together, leave now and don't read it. There's no need to be so hostile!
