Yeye was a carefree and smart puppy, but in order to protect his owner, Yeye fell to the sword of a bad guy.
Yeye really misses its owner.
In order to see and protect his master again, Yeye signed a contract with the system. Yeye went to various worlds to save higher-dimensional consciousness, but the system allowed Yeye to return to the time when his master was still there.
For this wish, Yeye traveled to many different worlds.
"World 1: Detective Conan"
The new owner that Yeye found was a dashing traffic policewoman. However, because the traffic policewoman was very busy with her daily work, Yeye was sent to live with the traffic policewoman's two younger brothers who were attending university in Tokyo.
Although the two brothers' daily life was a bit exciting (such as suddenly running PS: chasing a thief while walking Ye Ye), they liked Ye Ye very much and did not give up even if they were not at home often.
In order to better raise Ye Ye, they rented a house together in an apartment building...
