* CompleteMonster:
** [[DepravedHomosexual Dr. Gisuke Sasaki]], the doctor at the juvenile reform prison, [[BitchInSheepsClothing hides behind the veneer of a kindly old man]] but in reality is a cruel {{sadist}} who [[SerialRapist regularly rapes attractive male prisoners]], coerceing them by holding privileges and favors over their heads. One prisoner is eventually DrivenToSuicide thanks to Sasaki's molestations. Sasaki schemes with the warden Ishihara to murder anyone who knows the truth and after leaving behind the prison, continues [[WouldHurtAChild molesting young boys]] when conducting a political campaign.
** [[WardensAreEvil Warden Ishihara]] delights in exercising {{sadist}}ic authority over the prisoners by regularly conducting beatings or giving out [[DisproportionateRetribution punishments that are massively out of proportion to minor offenses]]. He deliberately throws away a key during a fire to try to kill Sakuragi and later [[spoiler:kills the honest guard Kumagai]]. Ishihara gives prisoners to Sasaki to rape and proposes murdering those who discover the truth to cover his tracks. When the initial hero, Sakuragi, finally defeats Ishihara, he gives the warden the evidence of Sasaki's crimes to make Ishihara leave his friends alone. Ishihara's response is to [[spoiler:stab him]].
* CrowningMusicOfAwesome: The opening definitely qualifies. Heck, it's even sung in SurprisinglyGoodEnglish.
** The ending too.
* MoralEventHorizon:
** Sasaki's [[spoiler:raping of inmates]] has pretty much put him across the line.
** Ishihara [[spoiler:throwing away the key to 2-6 during the fire evacuation]], only topped by his later action of [[spoiler:killing Kumagai]]. Even Ishihara himself seems disturbed by the latter.
* TearJerker: It's classified as drama. Better bring tons of tissue paper with you to wipe off your tears.
* TheWoobie: All of the main prisoners. Seriously.
** IronWoobie: And yet, they take it all in stride.
