To Onataru. The Soul of a Snake

When, due to the fault of humanity, an ecological catastrophe destroyed Earth and made life impossible, some had to leave their home planet forever for salvation, while others remained and perished.
Nikola is the last person who miraculously survived and boarded... a spaceship that flew in search of a new abode.
It is very difficult to find oneself on the road one day and know in advance that it will never end for you. Even scarier is when this road is an eternal flight among cold and indifferent stars. And it is even worse when your companions see you as the source of all their misfortunes, for you belong to the human race, and therefore you are to blame for the calamities that have occurred.
And yet Nikola is lucky. In this journey, he has friends — otherworldly, incredible, nothing like himself, yet the most loyal and best in the world. But what to do if a small and defenseless friend is in trouble that you are not aware of? And if at the same time you yourself desperately need help?
Nikola knows the answer for sure: still rush to save those dear to you. And then, as in a good old fairy tale, a kind and wise dragon will definitely come and shield you from all troubles with its wing.
