Heartwarming / The Lunacy of Duke Venomania

• Karchess once Yufina goes missing becomes much more dedicated to finding the missing women, even giving Elluka a What the Hell, Hero? when she tries to have them wait to confront Venomania while she’s in danger.
• The fact that it was partially The Power of Friendship that helped Lukana break free of Venomania's mind control, seeing her friend Lillien join the harem.
• We also see a little glimpse into Cherubim, aka Duke Venomania's life when imprisoned in the basement. Even though it was a lonely and sad existence, you can tell from his entries that the nameless guard (later revealed to be named Witnis Truth) who watched over him actually cared about him and took care of him, and was happy when Cherubim met and befriended his brother, Sateriasis. The boy says that even though he wanted to leave, it wasn't unbearable there because of the guard.
• Gumina's love for Cherubim, despite the deformity on his face.
