For anyone wondering about the context or just doesn't play Nikke and just looks at the artwork: In-game, Crown's kit works amazingly well with Naga, Crown's actually able to activate Naga's full kit; resulting in your DPS hitting like absolute trucks while protecting by shields AND healed as a result. Compared to Tia, who some people dislike using due to her strange mechanic, people outright started ditching Tia to focus on Naga with Crown.
