Kaiba/Tear Jerker


 * Kaiba has a few examples of this, but there's one that stands above the rest. Chroniko, a cheerful and optimistic girl, decides to sell her body in order to feed her family (literally, because memories can be transfered). She's killed when a Bastard scientist releases her memories after extracting them from her body. Her surrogate mother, her aunt, couldn't care less, since she considers it one less mouth to feed, and that she's taken care of her sister's kid long enough. However when her aunt restored her memories, the truth finally came out. She loves Chroniko, too much until she had to remove her memories of her loving Chronico so she can let her sell her body. Cue sad piano theme, tears, and name screaming.
 * That's one of the prime TearJerkers of the show, but it's far from the only one. The very next episode has Kaiba trying to go inside an old woman's mind to find the treasure her and her late husband hid. The problem is that she keeps speaking as if her husband is still alive. Finally,
 * It Gets Worse.
 * Episode 7...just...Episode 7.
