Killer Shark in Another World Manga Volume 5 features story and art by Kuboken.

There's only one way to take down an undead king. All you need is an undead killer shark infected with the S-Virus! Shiromi and her unintended familiar, Sharkiller, are working together to do their very first good deed by saving the Hamunanptra Kingdom from its corrupt ruler. But can she do so without accidentally murdering all of its citizens? And will this manga be able to go a full volume without making a very obvious Hollywood movie reference? The answer to both questions: I doubt it!
