Basilisk: The Kouga Ninja Scrolls/YMMV

The anime:

 * Complete Monster: Tenzen performs SEVERAL acts that easily qualify him like Princess Oeyo and Lady Ofuku may also count, given
 * Crowning Moment of Funny: From the same flashback above, Oboro gets so nervous about meeting Gennosuke that she develops the hiccups. After Akeginu tries to cure her (making her drink from a teacup with chopsticks across the top) and fails, Rousai and Nenki, arguably two of her most grotesque minions, do their part to help by leaping out and giving her the scare of her life. And it still doesn't work.
 * The entire episode in question is also Crowning Moment of Heartwarming. Considering that
 * High Octane Nightmare Fuel.: Every-fucking-where.
 * Puppy Love: Oboro and Gennosuke originally meet at around the age of 5. And are completely ADORABLE together. In no small part due to Oboro being a chibified Genki Girl... Who is introduced tugging on Tenzen's hair-spikes.
 * Tear Jerker: So, so many...
