Cardfight!! Vanguard/Tear Jerker

• Misaki's backstory being revealed via flashbacks of her parents' deaths that give her a breakdown until she has to stop what triggers them. Which is playing Vanguard.
• Episode 49, specifically Ren and Kai's backstory. Watching Ren transform from an Adorkable kid into his current persona is heartbreaking.
• In episode 50, Aichi's anguished rant at Kai. Effects of PSY Qualia aside, he was probably keeping most of what he said bottled up inside for pretty much the entire series...
