DMM’s popular web game and mobile game Touken Ranbu (刀剣乱舞) is going to make an existing character to be available for Kiwame (極), which is the last upgrade that a sword can get. According to the silhouette posted on the game’s official Twitter, the character is believed to be Daikokane Sadamune (太鼓鐘貞宗).
Daikokane Sadamune is a tanto (Japanese tactical short knife) that belongs to the Date clan. In Touken Ranbu, the sword can be acquired in the second battle of the seventh chapter.
The official revelation date and available date are still unknown.
