Here is my CS, though I'm not sure of the bounty. Given his background as a deserter from Marine Intelligence, what should his bounty be?

Bio: Handel grew up the son of a rich, militarily family. He learned to play string instruments when he was young and was set to become a great marine as his inevitable future career. He joined the marines, keeping peace and helping take down weak pirates in the name of peace and justice, eventually working his way up to being commander and second in command of a ship, where he supported his captain with brilliant strategies that prioritized the survival of the crew, making as few sacrifices as possible, and even preventing the loss of life of the enemy, earning his captain a reputation of mercy.
These strategies earned Handel a transfer from normal navy service into the intelligence division, where he became an agent of Cipher Pol 1, CP1. Here he utilized his ability to gather and exploit information in preventative schemes that stopped violence and uprisings before they began. Yet more and more, he was being asked to make difficult choices and to prioritize 'efficiency' and secrecy over the lives of his enemies and the soldiers he was responsible for. He went along with the flow, comforting himself with moral justifications until it became too much for him. He realized he had become a man who no longer saw other humans as people but as numbers in his calculations. He had been numbed to the atrocities he had committed in the name of 'justice'. In the middle of an important government operation, Handel let slip the amount of soldiers that would be sacrificed among the navy as well as spilling information to the enemy, giving them a chance to escape. This saved numerous lives from both sides, but convicted him of high treason. He had prepared for this outcome, and had asked his father in a letter to disown him, and then he slipped away and went into hiding before the marines came to arrest him. His family is safe, having enough money and clout to avoid trouble from the marines.
For the moment, Handel will be a traveling musician currently in Logue Town, trying to live on his own and see the world and understand the greater truth behind it. Seeing the presence of bounty hunters and possibly other marines that he knows, he will misinterpret their presence as an attempt to capture him for his desertion, rather than their original mission which is to capture Black Hole Merrick. The idea is that shenanigans will play out, and he will end up joining Merrick's crew.
Crew Position: Knows basic navigation, has some medical knowledge (mostly anesthesiology, pain management and psychosomatics) so he can be the navigator or assistant doctor but not the main doctor. He is better as a strategist, infiltrator or assassin.
Bounty: B- 5,000,000
Equipment: String Bass (Shield), Bass Bow (Sword), various other musical instruments, Den Den Mushi Set including several regular ones, a few baby ones, and a black one.
Abilities(Fighting Abilities): In close range, he uses a unique sword and shield fighting style. The back of his bass is steel-plated, he holds the neck of the base, planting the spike of the bass in the ground with it's back towards the enemy as a massive riot shield. The bow of his fiddle has a blade along its edge which he swings as a short sword. He is also strong enough to lift the bass and swing it around, using the spike at the bottom to impale foes.
Unique Skills: He has learned how to use vibrations and sound to affect various materials, as long as he tweaks the frequency. Typically, the stiffer and more brittle a material is, the easier it is to damage it with sound. He can imbue his sword/bow with a frequency by running it along the strings of the base and then striking with the sword giving it a property to easily cleave through the specific material it was tuned to. He can also launch out sonic attacks at range, but sound dissipates at range and is considerably weaker. He often plays on his own turf, scattering Den Den Mushi around to relay sonic attacks and create harmonic/acoustic zones where his sonic attacks are much more powerful. Knows various ways of using sound to affect the human body. Has the ability to infiltrate Marine ships and bases due to his background and intercept communications with his black Den Den Mushi.
Weaknesses: Requires information on the enemy to be most effective. His most powerful attacks take time or require preparation beforehand. He has limited long range capabilities, and is more defensive than offensive. He is only a decent swordsman at best, and relies more on surprise, advantage and finesse.
Other: He runs the role of 'support mage' for the most part. When he joins the crew and meets Eva Solkreuz and finds out about her power, he will start to develop a new method of team-fighting by imbuing her wind with sonic properties and possibly teaching her the useful properties of vacuums. He also knows various musical styles from around the world, including Elbaf war songs, which he can use to help Hertha fight at 120%.
