(1) Akafuda-nyan
A cat who has been around since before Ikeriri was founded, at the former Ikebukuro office.
He lived freely inside the Akafuda shopping center — his strong independent spirit was very encouraging.
Mr. Maejima often bought cat food for him there. He usually appeared around 7:00–8:00 PM and was gone by 9:00 PM.

(2) Chihaya Cats
Cats around the Yocho-machi and Chihaya area near the former Ikebukuro office.
(3) Amesho-nyan
Near the former Ikebukuro office, always tied on a leash outside a local bathhouse, cut off from the outside world.
When the building was renovated, he appeared through a hole in the wall — very cute and touching.
(4) Urayasu-nyan
A cat found near a client’s office in Urayasu. Always sleeping.
(5) Mr. Ari (Ari-nyan)
The Ikeriri mascot — a symbol supporting the Nagano base. Always relaxed.

(6) Shiro-nyan
A white cat found stumbling weakly along a road in Nagano in winter. With Ikeriri’s help, she recovered and found a new owner.
She has since been spotted walking energetically near the Nagano base.
