Pellegri led the U-TIC complex on Pleroma where MOMO was imprisoned until her rescue by Ziggy. Later, she commanded a dreadnaught pursuing the Elsa Van Brabant, carrying MOMO and other individuals. However, Tony, the Elsas helmsman, used extreme measures to evade the ship, causing Pellegri to lose pursuit. Additionally, the Durandal of the Kukai Foundation, commanded by Rubedo, began pursuing the U-TIC dreadnaught. Despite her dedication to U-TIC ideals, Pellegri often clashed with Commander Margulis' orders, which included using the Song of Nephilim against the Kukai Foundation. She also faced challenges from Jin Uzuki, Shion's older brother, particularly when U-TIC framed the Kukai Foundation for the destruction of the Woglinde armada caused by Gnosis.
