Tear Jerker / Kirby Adventure

• Keeby's death in The Beginning. Even if you did see it coming, giving that it was a flashback, and Keeby had never appeared in the comic before said flashback. Ulti even admitted that Keeby was introduced in the flashback solely to die.
• Vezo encountering Kiina again and discovering that her memories were wiped by Talzo's Gang and that she doesn't remember.
• While talking with Keito, NAVO admits that the only reason he's with Talzo's Gang is because they're the only ones who put up with him and that even they don't like him very much. Becomes heartwarming when Keito tells him that there are places where he'll be accepted and liked and convinces him to turn good. Later, at Keito's funeral, NAVO admits that Keito was the first person to treat him with kindness.
• Keito's death in Infiltration. Especially sad was his funeral where we got to see the members of the KAS, and a few other characters, pay their respects.
• Gigi admitting her involvement with Talzo after Keito dies as an indirect result of her actions. She even states that she deserves whatever the KAS does to punish her.
• Talzo's story turns out to be kinda sad. He was framed by Miracle Matter and Fune and was unjustly kicked out of the squad by Hali. He later somehow got involved with MSG, who forced him to go after the members of Division A. He doesn't even want to hurt anyone other than Hali, and later admits to Caiya that if it were up to him, Division A wouldn't be involved at all.
• Caiya's breakdown in Master Of Puppets. While her split personality is usually Played For Laughs, you don't realize how the smarter Caiya feels about the fact that she spends half of her lifetime uncontrollably living the life of a child. Her evil doppleganger making fun of her for it ends up causing her to collapse in tears.
