Tassera is a Blue Dragon and also a Mage. Recently, she even improved her spellcasting level by drawing a Comet Card.
Although her main focus is on the schools of shaping energy and illusion magic, she is also adept at using Mysterious Steps. Even if she encountered some powerful demon that she couldn't defeat, escaping would still be relatively easy.
Leon merely thought of Tassera but wasn't too worried about her.
Speaking of which, even if he were to worry about her, it wouldn't serve any purpose. Tassera currently resides in the Red Crown Desert, a bit far from Watchtower Port. Unless there was some dire news, it would be impossible to trek over such a long distance.
