Tag jibowu and costain

I'm assuming you want me to tag the characters Jibowu and Costain from the Shadowhunter Chronicles series by Cassandra Clare.

Jibowu: Jibowu is a character from the Dark Artifices series. He is a Shadowhunter and a member of the Los Angeles Institute. He is also a close friend of Emma Carstairs and a potential love interest.

Costain: Costain is a character from the Infernal Devices series. He is a Shadowhunter and a member of the London Institute. He is also a close friend of Will Herondale and a skilled fighter.

Let me know if you need any more information or if there's anything else I can help you with!
