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