We have developed a new framework of antisymmetrized molecular dynamics (AMD), to adequately treat the $I=0\overline{K}N$ interaction, which is essential to study kaonic nuclei. The improved points are 1) ${pK}^{-}∕{n\overline{K}}^0$ mixing and 2) total spin and isospin projections. These improvements enable us to investigate various kaonic nuclei (${ppnK}^{-}$, ${pppK}^{-}$, ${pppnK}^{-}$, ${}^6\mathrm{Be}K^{-}$, ${}^9\mathrm{B}K^{-}$, and ${}^{11}\mathrm{C}K^{-}$) systematically. We have found that they are deeply bound and extremely dense with a variety of shapes.
