mangadex.org
A story about a little summoner girl that accidentally summons a shark from another world as her pet that has all of the powers seen in shark movies in the modern world.

Translation has resumed after one and a half years! (with a chapter parodying isekai tropes / protagonists!)

If you enjoyed Isegure, this may be your cup of tea.

Be warned that it can get rather gory at times.
