tiki_(adult)_(summering_scion)_(fire_emblem)
Adult Tiki from Fire Emblem specifically when dressed in her summer attire from the Fire Emblem Heroes 2017 Ylissean Summer banner.
The outfit consists of a red bikini with a front-tie top, a pink sash, red and heeled sandals, triple anklets, bracers, and a golden choker.
May feature her weapon: a long stick and a watermelon.
Note that it's possible (especially for older artwork), to depict Adult Tiki in a swimsuit without it being the one described above, in which case this tag should not be used.
