Luka
in your Demi Human form
at ages 3, 7 and 14
is Yulo's only friend
and her 1st love interest

Luka was the "Imaginary Friend" of Yulo and Sayori's younger sister, Little Yumi.
q always met with Luka in the forest
where he showed her all the life and worlds within her but obviously
The mother of the 3 brothers worried and made Yulo see where her little sister was
and that's how they met after Luka accidentally scares Yulo by showing up without the little wolf appearing
since then both felt something new as soon as they saw each other and so
Yulo went on to accompany his sister on adventures in her feral form through the forest. with even
Just the 2 meeting at dawn to play together
Being Luka the 1st and only friend that Yulo managed to have
that no matter how cranky and closed it was Luke has never felt bullied
but as they grew everything was changing around them
the premature death of the puppies' mother distanced them from the forest
consequently from luka and Luka's problems also started to appear
with the deforesting of your home and even powers with hunters
Luka was forced to also go to the urban area having to survive that new reality
learning things and having to do things I would never be proud of
until the adult stage that's when he finally had a reunion with his 1st Love and best friend
