if you mean which one is my favorite, i enjoy song 9 (cannot remember the full name) a lot! but i also love boku no weak point, ai☆$!! and love and peace! but if you mean who i would want to see in each one, mainly rooting for midori in boku no weak point / love and peace , mao and mitsushino in ai☆$!!, and nazuna in it's (k)not love! i don't care too much about the other placements as long as already established units aren't mushed together
