Tag used for Lilina (Fire Emblem) from Fire Emblem specifically when dressed in her summer attire from the Fire Emblem Heroes 2019 Summer Refreshes banner.
Can typically be identified thanks to the attire's characteristics: a red Bikini with a Side-Tie Bikini Bottom, Gladiator Sandals, a Head Wreath made of red flowers, a Palm Leaf, and a see-through Capelet around her shoulders.
Note that it's possible (especially for older artwork), to depict Lilina in a swimsuit without it being the one described above, in which case this tag should not be used.
