arc i. daywalker
In her hiatus from the X-men, Kira visits her family estate in San Haven to settle her affairs and make sure the family of her childhood friend is well off in her home. On the way back through Los Angeles, Kira has a close encounter with a Reaper carrier, a vampire infected with a deadly virus that transforms them into a creature with an endless appetite for human and vampire blood alike. After it's slain, she narrowly escapes being cut down by Blade himself, and sticks around in town to investigate the growing epidemic among her kind.
Scoping out a popular vampire safehouse, the House of Pain, the party turns fatal as the Reapers attack. A countermeasure reveals itself in the form of the Bloodpack, a private paramilitary of born vampires, combatting the Reapers no matter the cost of casualties. Kira proves herself a valuable ally, beheading a Reaper, and with the loss of Bloodpack member Priest, she is allowed to join their mission.
When patient zero is revealed to be the vampire Lord Eli Damaskinos' genetically engineered son, Kira is subdued alongside Blade and Whistler. Imprisoned, her blood is harvested until Whistler frees her. She aids him in the destruction of the facility, feeding on the familiar guards and destroying the daywalker prototypes. After Nyssa Damaskinos' self sacrifice, Kira prepares to take off again, but not before leaving Whistler her contact information to reach her should anything that threatens the human race like this arise again.
arc ii. nightstalker
After leaving the X-men with a heavy heart, Kira receives word from Whistler. She arrives too late, to hear of the explosion that claimed Whistler's life alongside destroying their homebase, and to witness Blade be taken in by the police. She makes an elaborate effort of sneaking into the heavily guarded police station, only to find Blade, even in his drugged and weakened state has made a considerable effort to leave by himself. The two are interrupted by the young and human members of the Nightstalkers, a group of vampire hunters and occult experts banded together under one cause.
Blade and Kira are escorted by Hannibal King to the Nightstalkers' base, where they are informed by sorcerer supreme Doctor Strange of the threat that has brought on a rise in vampiric powers making bolder attempts to eliminate Blade from the picture. Dracula rises, and with him so do the amount of fools who wish to subjugate the human race and cover the world in eternal darkness. Kira keeps her objections mum, only to Blade and Hannibal, that something else is afoot that has her father acting like his old self. The group rests up and follows leads in the morning, only to realize they've been separated from each other intentionally.
Kira is tested, and spars with her father, tempted at every turn to join him, be a family again, and take on the responsibility of this planet and all it's creatures. It's what her father would have wanted, but it's not him that's saying it. It's not his turn of phrase. It's a shadow who still clings to a crown. Dracula leaves her to taunt Blade and Hannibal King individually, and as they regroup, he leaves to attack the Nightstalkers headquarters. The occultists are slain. The hunters too. The scientists hang onto life by a thread.
Dracula sheds his disguise and is revealed to be Varnae, the original vampire. His only weakness is to trick his body into eating itself with an unstable, airborne virus that'll kill every vampire in the vicinity. With closure her father still rests dead, Kira evacuates the humans, and leaves LA for Genosha. She calls Hannibal who verifies Blade is alive and refuses to work with him again.
