The savagery of the Red Moon Fragment turned the White-crowned Crane [Walnut] into the most difficult magical creature in the zoo to handle.
Its fierce and fiery temperament held strong hostility towards other creatures, even its keepers.
It even killed another White-crowned Crane that tried to pursue it.
A year ago, this very Walnut, after being injured, accidentally ended up in the treatment group Chloe was responsible for.
Recalling the past, a slight smile appeared on Sean's lips.
That treatment session was nothing short of a disaster.
When he heard that Walnut had mingled with the newcomers, he panicked and rushed over to try to stop it.
And then, in the animal hospital, he saw a young boy, covered in peck marks, carefully healing the wounds of the injured Walnut.
From struggling desperately, to gradually hesitating, and perhaps eventually sensing the boy's goodwill, it no longer attacked.
