Spoiler!
Seoyoon found out early on that Irene is of higher rank (S++ rank then turned to SS rank). Of course the selfish bxtch that she is can't have that so she tried to travel MULTIPLE times to catch up on Irene's rank.
Later, after Irene, Ciel and the gang (mostly Irene and Ciel) killed the monsters and closed all the portals where the monsters were coming from, only Seoyoon's portal was open. She tried to travel dimension again for one last time to gain the SS rank but Irene did not take her shxt anymore. Seoyoon's phone already died down and the last portal was closing. As punishment, she took both arms of Seoyoon while she was on the other side of the portal so that when the portal completely closed, both her arms will be severed from her.
On earth if you are a guide but unable to join expeditions due to disabilities, you will be used in the worst way. Like a living battery. Irene says that it's the bottom of ranks on earth.
She figured that that is the best punishment for Seoyoon.
