Ship Leesoo (십이수, Shib Yisoo; "Shibisu") is a C-rank Regular. He is relatively weak, yet possesses a great ability to deduce and an intellect on par with Khun Aguero Agnis's.
Leesoo looks like he is wearing the same outfit as he did in Part I, however, with closer observation, his jacket now has a zipper on the front. In the Workshop Battle he wears a grey jacket with his hands often in his pockets, also been seen in the swimwear in Archimedes piscina. His face is also more angular and less spherical than when it appeared in Part I.
