History TearJerker / Pupa

* The "Maria's Island" special. It reveals that Maria/Ai was feared by her mother for being a CreepyChild with a LackOfEmpathy. And she got scarred in the face after she deduced that her brother Makoto [[ADateWithRosiePalms did things]] with dolls. Feeling guilt for scarring her face, Makoto develops incestuous feelings towards her, but Ai becomes too fixated on the Pupa monsters to notice his feelings. In order to continue being alongside her, he stays as his assistant... [[spoiler: her faithful assistant Hotoki.]]

* Shiro's past. [[spoiler: An orphan adopted by to Maria's grandfather. For years he was locked in his house, physically abused, experimented on and treated as a plaything. Also, he became convinced that the abuse was Genjurou's "love" towards him, so he wants to show that love to Utsutsu.]] Hence why he is so unhinged and believes that hurting those you love is the greatest form of affection.

** [[spoiler: How about the reactions to everyone after Utsutsu and Yume disintegrate? Yuu accepting calmly that his mate now loves someone else. Shiro is broken and devastated, since in the end he was unable to save his son. Sachiko is watching the red butterflies with a smile in her face....unaware that those butterflies are her son. And then the butterflies reach the school. Utsutsu's best friend, Yuuhei sees them and realizes that Utsutsu is not coming back.]]

** We also see a glimpse of young Shiro just as he's going to be adopted by Genjurou. Genjurou expresses interest in making him his new inspiration for his paintings and takes him away. Shiro can just look back at Makoto, as if he were asking for help. But Makoto just looks away, lamenting that Genjurou will break the boy in the future. The next time we see Shiro, [[ForegoneConclusion the damage has already been done]].

** [[spoiler: However in the end, Utsutsu and Yume were able to overcome their monster instincts and died with a smile. Counts as DyingAsYourself.]]

** [[spoiler: Or that's what Utsutsu thinks. The truth is that Yume is an amnesiac monster incarnated as a human and her birth gave problems to the Hasegawa household, since Shiro believed her to be HeroicBastard and that Sachiko cheated on him. While Sachiko went into despair upon witnessing Yume's antics as a monster. And while Shiro is a jerk, the scar in Utsutsu's eye is not his fault. Because it was YUME'S DOING. In resume, all the problems in Utsutsu's life are Yume's fault.]]

* Yuu [[spoiler: is eaten alive by Utsutsu in one of his rampages, after the latter starts becoming a monster.]] And after they're confronted with that fact, not even Utsutsu or Yume care about it. Gladly, because he is a Pupa monster, he survives.
* Shiro giving Utsutsu a NoHoldsBarredBeatdown, as he [[spoiler: proclaims that pain is love and he loves his son so much. Then, we see a flashback of Shiro kicking a toddler Utsutsu in the face....which inmediately turns into Genjurou whipping a young Shiro]].

** Oh, it's more than that. After [[spoiler: the truck runs into the kids, Yume regenerates inmediately due to her HealingFactor, but since Utsutsu is a human, he is about to die (with broken teeth ad his instestines pouring out) and tearfully begs Yume not to abandon him like her mother did. Yume has a change of heart and decides to revive Utsutsu...by turning him into a monster like her.]]
* The BittersweetEnding. [[spoiler: Utsutsu and Yume devouring each other as they dissintegrate into butterflies.]]
** [[spoiler: How about the reactions to everyone after Utsutsu and Yume dissintegrate? Yuu accepting calmly that his mate now loves someone else. Shiro is broken and devastated, since in the end he was unable to save his son. Sachiko is watching the red butterflies with a smile in her face....unaware that those butterflies are her son. And then the butterflies reach the school. Utsutsu's best friend, Yuuhei sees them and realizes that Utsutsu is not coming back.]]

* Shiro's past. [[spoiler: Given off by his own parents as a baby to Maria's grandfather. For years he was locked in his house, physically abused, experimented on and treated as a plaything. Also, he became convinced that the abuse was Genjurou's "love" towards him, so he wants to show that love to Utsutsu.]] Hence why he is so unhinged and believes that hurting those you love is the greatest form of affection.

** In a rather sad and twisted way, [[spoiler: Utsutsu becoming a Pupa monster in front of his father showed that even Shiro is capable of love, even if it's distorted by the childhood abuse he's suffered through.]]
