Dr1: 1,000 blows. Yikes. It's over the top, bloody, and painful to watch.

Sdr2: Hmm....either One Woman Army or Insert Coin. In One Woman Army, peko dies thinking that she killed young master (it's okay my heart was dead already-), and i-she-there was just so blood ;-;. In Insert Coin, there's a firing squad and there's Pac-Man and then there's Tetris?!? And like, she was able to escape two of them and there was eventually no where for her to run and-I-ugh that was...
Yikes.
(I'm not even going to go into the anime o.O)

V3: Kaede's execution. Frick. That was the first Danganronpa execution I ever saw and it was-brutal. I can't even imagine how painful that must have been.
