We develop a three‐dimensional    N  =  4    theory of rigid supersymmetry describing the dynamics of a set of hypermultiplets    (   Λ  I   α   α  ′α  ̇   ′,   ϕ  I   α  A    )    on a curved AdS 3  worldvolume background, whose supersymmetry is captured by the supergroupD  2    (  2  ,  1  ;   α   )    . To unveil some remarkable features of this model, we perform two twists, involving the SL   (  2  ,  R  )    factors of the theory. After the first twist, our spacetime Lagrangian exhibits a Chern‐Simons term associated with an odd one‐form field, together with a fermionic “gauge‐fixing”, in the spirit of the Rozansky‐Witten model. The second twist allows to interpret theD  2    (  2  ,  1  ;   α   )setup as a framework capable of describing massive Dirac particles. In particular, this yields a generalisation of the Alvarez‐Valenzuela‐Zanelli model of “unconventional supersymmetry”. We comment on specific values of the combination    α  +  1   , which in our model is related to a sort of gauging in the absence of dynamical gauge fields.
