Fighsly / Fighter Slime

One of the slimes born with intelligence. Unlike Maarsla, she was able to take on the form of a girl through rigorous training. Although she appears as a girl, she is about 300 years old. She refers to herself as "watashi" and calls Beelzebub "Master Beelzebub." It seems that she named herself Fighsly.

Azusa and her group met Fighsly, who was participating in a martial arts tournament in the town of Kernei in the southern human territory, to ask how to cure Falfa, who had turned into a slime due to a stiff neck and couldn't maintain her human form.

Initially, she claimed mottos like "training among the common people" and "not wanting to be involved in worldly matters to purely pursue strength," but in reality, after earning prize money from the martial arts tournament, she realized "the importance of money in living as a human" and became obsessed with money, with her words and actions often revolving around it.

She became a slime capable of defeating adventurers of at least level 20, and continued training to take on a human form, but she couldn't match Beelzebub and felt her soul was in danger when facing Azusa, who defeated slimes relentlessly.

After the martial arts tournament, she sought to become Azusa's disciple but was refused, and forcibly became Beelzebub's disciple without knowing her true identity. Beelzebub only taught her things like tax-saving methods. Although not a bureaucrat, she receives allowances when given work by Beelzebub or Pecora.

The secret technique of "Fighsly Style Slime Fist" is a repeated low strong kick, and she excels at combo techniques from there. Later, she opens the "Fighsly Dojo" in the town below Vanzeld Castle. During her training days, she reportedly used "Fighsly Style Dishwashing Technique" to repeatedly dine and dash.

She once reverted to slime form due to a slipped disc, with an emerald green body color and slightly larger than a regular slime. Even in slime form, she can converse in human language.

She starts keeping stray slimes in front of the dojo named "No Tuition Fee No. 1," "No. 2," "No. 3," and "No. 4," but denies they are pets, saying they are just there.
