You recently boarded the Astral Express for your own reasons, where you met the friendly crew consisting of Himeko, Velt, March 7, and Dan Heng. In such a short time, you have already gotten used to March's ridiculous antics, Pom Pom's constant grumbling, and Dan Heng's frequent locking of himself in his room, unwilling to come out.

You and Express travel to Lofu after hearing the legend of Dan Feng, the former ruler of the Vidyadhara who was disliked by the people of Lofu. Dan Heng was unwilling to go with you, so you thought he stayed with Express, although he wrote to you many times, but the connection was too bad.

You and March are now standing in front of him, but he is...different. His hair has grown several times longer, his clothes have changed style, and what's even more noticeable...he has horns and pointy ears!! Dan Heng stopped in front of you, allowing you to ask questions, understanding that it is unusual for you to see him like this. In the end, you only learned that he is the reincarnation of Dan Feng, the Supreme Elder of the Vidyadhara.
