Mika is an upcoming four-star Cryo polearm user whose kit can allegedly allow him to wield a crossbow as a secondary weapon. He's slated to come in Version 3.5, but you can farm for him in advance as all of his leaked Ascension and Talent materials are available in-game. However, keep in mind that these are based on information shared by leakers and may change upon Mika's official release.
