General summary of what it's about: one of Yoru's main ancestors is still alive for some reason, probably due to the long contact he had with the mask. He serves in the special military forces and has an acquaintance who participates in the Valorant Protocol (for now, Tejo). This person recommends him, and he enters replacing his successor, the Yoru we know.
Lore: Yoru (ancestor) goes to the Valorant base. There, he finds his successor with his old mask. When he touches it, the paint done by Yoru comes off completely, revealing its original color: a very shiny bronze. An energy never seen before is released by the mask.
This new Yoru has a more polite and calm personality, not liking to talk much. Due to his long experience, his skills are extremely advanced.
While the current Yoru returns to Tokyo to continue the standard life he already lived there, he still makes some visits to the Valorant base.
