Hassfuer appeared later than all of my ten cuties in the White Town.
First of all, when he appeared, he greatly helped Severin, supported him morally. But then, when they all began to live in another world, it especially changed a lot, both externally and internally. His character is rude and grouchy, until he shows his courage and sympathy. This makes him cute in my eyes. But in general, if you delve into a istory, then he, being reborn in another world, at some point encountered Eveline, Karmello and Lucian, after which they all sought to return home to the White Town, but got stuck in a dimension that is "home" lizards (although it's better to call it a place of work, namely a citadel).
When they managed to leave this citadel, they eventually got to know me again and with those cuties that lived in The World of Terra, also not remembering me for some time. So now he lives with Seventh in his separate house, periodically visiting Belgrade, where everyone else lives.
To be honest, I forgot a little about the details of how they got from the citadel to The World of Terra, but I think I'll try to remember and write about it, because it is directly related to the history of The World of Terra and, accordingly, it is very important.
