[You help 'Shuten-doji' to its feet and inform it about the Evil God ...]
[...]
[After a brief exchange, you learn that all the members of the 'Shuten' clan were sacrificed in the divine war, leaving only it who was still an infant at the time.]
[It grew up in the mountains, spending its days with beasts, living on raw flesh and blood... Until more than a decade ago when it awoke its inherited memory of the 'Shuten' lineage, gaining human intelligence.]
[It learned about the defeat of the Dragon God, and the outside world is now dominated by believers of the new gods, so it had to remain low-key, assuming a human form to occasionally descend the mountain.]
[Despite its caution, it accidentally alerted others and got surrounded by the general's soldiers...]
[Now, your presence has filled it with hope, and 'Shuten-doji' can't wait to storm the Capital with you and eliminate the General.]
