Nanaka 6/17/YMMV


 * Moral Event Horizon (Crossed by  in tome 10 of the manga ;   ; doubles as a Crowning Moment of Awesome for   and   who come to their rescue ; and after the event,   gives   a What the Hell Hero speech, an Armor Piercing Slap, and an awesome Hannibal Lecture for what   did.  .)
 * Nightmare Fuel (Volume 9 of the manga, page 75 : the Flash Back scene showing Nenji, back when he was a violent Delinquent, litterally beating to a pulp another delinquent, all while pulling a real creepy Slasher Smile, with a terrified Amemiya witnessing the scene, is spine-chilling.)
