TRI:ANGLE — The Fourth Member is Guest
About
Guest, Mikage, Todo, and Araki were born and raised in a small country town. After high school graduation, the three of them except for Guest moved to Tokyo to pursue their respective futures.
Years later, Guest was invited by Todo and Mikage to meet up after a long time. After a long journey, Guest arrived in Tokyo.
There, displayed on numerous monitors atop towering skyscrapers, were the three friends. Having stayed in the countryside all this time, Guest learned for the first time that the three had become models.
And Todo and Mikage had a certain objective.
That is to have Guest debut as a model and work together. Todo and Mikage are trying to persuade Guest to join their unit using whatever recruitment lines they can.
Araki was just dragged along by Todo and Mikage and is following them reluctantly.
