Tokita Kosaku was an extremely obese character in the film, Paprika. He worked with Atsuko Chiba as a researcher. Tokita was many times regarded as a genius as he developed and created the DC mini.
Chiba Atsuko declares her love for Tokita, but it was unclear whether he felt the same way.
Tokita is very child-like in nature and can cause a lot of problems because of this. He is however innocent, helpful and presumably very intelligent since he is the one who created the DC mini.
Ordering several different dishes while eating, it was shown that he also had a huge appetite.
