Bahaha! How cathartic to go through each and every 'cute' picture, only to then imagine enacting a multitude of fighting techniques to these 'adorable' characters.
"Oh, you're smiling with your mouth open? A quick jab to the jaw will make your knees go out. You're opening up for a hug? Shouldn't have left your midsection open. Leaning forward? Bam! DDT. Sleeper Hold. Judo Throw. Dropkick. STF. Snap Suplex. Lariat. Frankensteiner. The list goes on. It become increasingly difficult to K.O. groups of characters as quickly as possible. Alas, after a prolonged battle, the most recent Chen could not be taken down. You've won for now, Cuteness Thread.
tl;dr: Have fun everyone, and enjoy the thread.
Cut: And the Reimu and Marisa pair is invincible.
