Yagotter

The main character of Otterland! This little otter here used to be human, but got isekai'd into Otterland. He loves otters above all and wants to pet them all. Now, living as an otter, he tries his best to fit in (which he often fails to do), have fun with the otters, befriend them, and unite and pacify the gang wars happening around the city.

He hates fish, which complicates his life as an otter. He always makes a silly face when he is around otters, and that basically means he has a silly face... all the time lol. He also thinks his snout is a great weapon (well, a great anything) and is often seen beating his snout against his enemy in a fight, or even our of a fight to be honest - according to him, it's also to show affection. 

He's quite a weird guy...
