Tear Jerker / Summer Wars

• Sakae's death. Also, Sakae's will being read to the family, where she pleads to them to take Wabisuke back into their lives.
  "I want all of you to sit together and eat as a family. As you have always done. The worst things in this world are being hungry and being alone."
• Perhaps even worst than her death itself, there are her family's desperate attempts to save her. They're all crying "Grandma!" except her daughter, crying "Mother!"
• The scene where Natsuki starts crying, and then Kenji holds her hand as she's crying, right after Sakae's death, is one of THE saddest moments in anime history! And in the English version, the tears are for REAL. ^note Brina Palencia channeled her very sad side by remembering the death of her own grandmother and that's what you hear in the dub.
• The manga adaptation makes Sakae's death worse when Kenji has a nightmare where he's alone in a dark, destroyed OZ, the bodies of defeated avatars all around him (King Kazma included) and finds Sakae attempting to face down Love Machine all on her own with the same naginata she'd pointed at Wabisuke. Cue Kenji jerking awake only to realize something's wrong.
• Seeing the sardonic and to this point quite unlikeable Wabisuke have a BSOD once he finds out Granny Sakae just died. After rushing back to the house (and by the look of the car, going through anything in his path), he cries out for Granny with such a look of despair on his face it breaks hearts.
• In a similar vein, seeing reclusive and sharp-tongued Kazuma break down completely after Love Machine defeats him a second time and devours King Kazma. He breaks down crying not only because he lost—and to him that's kind of a big deal, since many users know him as a world-renowned fighting champion—but also because he feels that he couldn't protect his mother and unborn sister from the incoming threat.
• The Casino scene, where Natsuki loses thousands of accounts due to a momentary distraction. As the computer says 'insufficient funds, do you wish to quit?' You can see a silent It's All My Fault written on her face.
• Look at the funeral. Look at the length of the line. And remember that aside from the family members who were planning to come anyway, all those people seem to have managed to get there overnight, even though the country is probably still disrupted. Oh, right, Sakae was a Japanese Medal of Honor recipient, wasn't she?^note The Purple Ribbon they mention is for contributions to the arts and academia. Now, did she help more people during her life, or by motivating her family to work together and stop Love Machine?
