Seriously. One last punch to the gut eh.
My guess is
Miku, Nino, Ichika, Eatsuki, Yotsuba
Miku does that hand gesture where her hands meet + stoic face,
Nino does that pompous pose with her hands,
Ichika, (prolly looking into it too much but the eyes are what always stands out)
Eatsuki does that cross arm thing,
Yotsuba just because I have love.
Yes I have fucking love. Dont me.
