Ultra Dimension Action Neptunia U(JP): Let’s Last Boss! 超次元アクション ネプテューヌU：ラストボス

I (think) I finished the game. It was way too easy. (I might complain to Compile Heart and Tamsoft) I used collaborative special attack(Noire and Dengekiko) four times to kill this boss. (With close to max stat upgrades as well)
