addedAs the spring air fills the first week of April, I have returned with a new webtoon featuring Airan’s second story, '364. The Secret of the Blue Powder.' We have prepared this teaser in a lighthearted art style, distinct from the main game, for your enjoyment!

It is quite different from the image of an elegant mage we usually imagine, isn't it? However, her cold, indifferent tone and sharp judgment are every bit the marks of a skilled mage.
