We continue our investigation of the 4D effective field theory for closed string axions in type II compactifications with D-branes. The inclusion of Stückelberg couplings for the axions requires the presence of chiral fermions at D-brane intersections, whose interactions at strong non-Abelian gauge coupling induce mass terms for the axions and scalar chiral condensate excitations, dubbed infladrons. The setup allows for a realization of naturallike inflation with a closed string axion as inflaton and a flattened scalar potential due to the backreaction of the more massive infladrons. We further point out that this large field inflationary model is not compromised by axionic wormhole corrections.
