Awesome chapter, and wth did the frogs summon? "The three of us can summon something pretty strong", it didn't look like it was big, but it had a big scroll and a cloak with flames on it... like minato's cept his was white not black. But still perhaps its a human summon of some sorts.
Also in the smoke cloud you can see 3 shapes of the same size.
Can't wait till ch430.
