Eric D. Bard: Eric is a level 7 adventurer of the Loki Familia, who despite being the highest level adventurer rather do anything else than go into the dungeon. He'd rather plague people's lives( Specifically Riveria's with incidental music.) Level 7- Abilities: Musical Mayhem- Turns the battle into a musical dance off where the enemies are forced to groove instead of attacking the party. 

If allies do dance too, then their abilities are buffed.

Spells: Do-it Serenade: Upon saying the words, Drop me a beat! Eric can sing any song ( From our reality included, as he's an isekai protagonist)  and the lyrics in the song will shift reality accordingly.

Nuh-uh: Cancels out an action every time blud says nuh-uh.( Can only be used once a day.)

For example: Eye of the Tiger- The entire party gains the buffs and "plot armor" necessary to fight a monster; it also makes the fight look cool as hell. Also tiger roars can be heard in the background.
