Pretty sure I'm the minor character...

44 is here to assist RayRay through the assigned worlds! 44 is smart system! Eh? RayRay, why is the protagonist following us? Eh?? RayRay, why do I sense the protagonist around us? Eh??? RayRay, What is the protagonist doing in your room?! 44 is innocent, 44 is innocent, 44 did not see anything, did not say anything...      >->

Ray Lee: I haven't done anything to help or harm you, why are you following me?

Protagonist: You don't need to be shy... really... :)

Female Lead: I! Support! This! Ship! Let! It! Sail!
