  We perform an exotic dualization of the Ramond-Ramond fields in type II
double field theory, in which they are encoded in a Majorana-Weyl spinor of
O(D,D). Starting from a first-order master action, the dual theory in terms of
a tensor-spinor of O(D,D) is determined. This tensor-spinor is subject to an
exotic version of the (self-)duality constraint needed for a democratic
formulation. We show that in components, reducing O(D,D) to GL(D), one obtains
the expected exotically dual theory in terms of mixed Young tableaux fields. To
this end, we generalize exotic dualizations to self-dual fields, such as the
4-form in type IIB string theory.
