  We prove the existence of all companion points on the eigenvariety of
definite unitary groups associated with generic crystalline Galois
representations with possibly non-regular weights under the Taylor-Wiles
hypothesis, based on the previous results of Breuil-Hellmann-Schraen in
arXiv:1702.02192 in regular cases and the author in arXiv:2103.03823 in
non-regular cases.
