Busou Renkin/YMMV

Alas, Poor Villain: Washio, the eagle homunculus. Don't worry, he came back.
Designated Protagonist Syndrome: Kazuki
Crowning Moment of Funny: MANY, but especially the meeting of Kazuki, Toriko, Papillion and later Bravo in the Burger Shop.
Crowning Moment of Heartwarming: Kazuki and Tokiko delivering the flowers from Mahiro and Co. to Ouka.

Kazuki: You know, once you get better, we should all hang out sometime. We're your friends now. You don't have to be alone anymore. We're here for you.

- Tears of happiness from Ouka follow.
- Tokiko using Bravo's Silver Skin to rescue Kazuki, adrift in space, and reunite with him.

If you die, I'll die too... No. I want to stay alive, next to you. We'll never be apart again. [they touch their hands] Now and then... You and I... are one.

Crowning Music of Awesome: MAKKA NA CHIKAI. That is all.
- Also, "Hangeki" on the official soundtrack.
Ear Worm: Whoaaohh whoa-oh whoaaohh whoa-oh da-danana da-daaaaa!
Ensemble Darkhorse: How can you not like Papillon?
- Moonface plays a small role in the series but is one of the most memorable characters, due to his distinct appearance and mannerisms.
Fan Nickname: Tokiko, aka "Scar-tan".
High Octane Nightmare Fuel: The Hayasaka twins' backstory is fairly disturbing.
Ho Yay: The Furo Scene described in the Foe Yay entry. Actually, size comparison seems to be a recurring sub-theme in the series: in episode 18, we see Kazuki and Gouta taking a leak in a river, side by side. Gouta turns to take a peer at Kazuki and immediately thinks that, compared to him, he's an "UNDERDOG!!!" (complete with English text!)
Les Yay: Mahiro seems to like girls, especially Tokiko.
Narm: Could anyone take the fight between Papillion and Dr. Butterfly in episode 13 seriously due to their flamboyant dress and attack names?
- Yes. And that's the most disturbing part...
Tear Jerker: Tokiko screaming for Kazuki towards the end of episode 24.
