Yes Ion's ability is similar to Devil May Cry's Vergil's Summon Swords
~ Feeling shunned by master Arturo, who had taken more of an interest in Zephyr and was giving him special training, Ion was left alone to figure out how to develop his more advance skills. Taking an interest in a technique he discovered in his early teens, Ion would spend hours perfecting his storm of swords, as Zephyr had a leg up with the development of his own technique under the guide of master Arturo, Ion had to keep up and he had to do it on his own. This would keep Ion very motivated for sparring day, the day of the week where he would face off against Zephyr to test how much they learned, honing his craft to use the lightning swords for both offence and defense, Ion stunned master Arturo with the capabilities he was able to develop on his own, as the lightning sword rain never lost him one bout, stunning both the master and his protegee ~
