Owl Kurotsuki... belonged to the "Kagehana" clan until 11 years ago...
The Kagehana clan was known as a small, disciplined clan loyal to itself, with a history dating back exactly 65 years. But one night, news spread that would shake the clan. "Owl Masaru" betrayed the clan.
Owl Masaru was Kurotsuki's father. As soon as the news spread, Owl Masaru was captured and brought before the clan leader. The reason for Masaru's betrayal was never revealed; it was simply stated that he had betrayed the clan, which naturally raised suspicions.
The Clan Leader stood up and took his katana in his hand. "I protect my clan, I protect my people... and I will show no mercy to anyone who stands in my way... even those closest to me." At that moment, Kurotsuki woke up to the Clan Leader's voice and went outside. He saw his father but couldn't take another step forward and began to watch silently.
"I, Clan Leader Jin Taichi... sentence Owl Masaru, who betrayed our clan, to death. Let us hear his last words."
Kurotsuki watched the situation in shock.
Masaru stood up:
"I won't say much about this matter, because no matter how much I speak, you will all believe the Clan Leader. So I will say only one thing: I would never betray my clan, I would never betray my comrades... Now I am accused of treason and I will die. I have no regrets, but remember this: even if I die, my ghost will destroy this clan... A true Ghost..." The Clan Leader plunged his katana into Owl Masaru's heart...
After everyone had left, Kurotsuki approached his father's body lying on the ground... "Father..." He sat down beside his father, his voice trembling. He began to cry, embracing his father. He took the "Shiranai" Katana standing beside him; it was his father's final legacy to him...
"Father, Father! When will your katana be mine?"
Masaru laughed:
"Hahaha... When the time comes... When the owl is no longer here..."
After recalling this memory, he looked at his father's body lying on the ground once more. Taking the katana, he began to run outside the clan. As he ran, he swore an oath to himself:
"To find out why his father was killed and... to destroy the entire Kagehana clan..."
