Tsunayoshi, Leyasu and Tsunako. The Sawada Siblings known to be popular and charismatic except one. Sawada Tsunayoshi born quiet and sickly has always been pampered by his family. Being born smart and a genius, he graduated earlier than his siblings. Leyasu and Tsunako born in the mafia swore to themselves that they will never reveal their brother to the underworld but little do they know that Tsunayoshi, who is shroud in mystery and power, is more deeper in the mafia than themselves. It all started when The Sun Arcobaleno appeared.
Chosen to carry the curse of all
Hidden by the bloodied veil
Loved by the others and more
Let fate take its place
For the time of meeting is drawing near.
Turn back time and worlds
To save the boy who carries the curse.
The Sea, The Clam and The Rainbow
Sought for him longer as they were born
One by one they met but one has never been seen
The sky who gave them light is somewhere in this parallel world
