Neon Genesis Evangelion - The Shinji Ikari Raising Project #9

Plot

Face the thing that should not be! At last, Shinji, Rei and Asuka are being trained for actual combat, gats in hand--stalking a giant gelatinous creature with a spherical "core" they must take out. If this kind of mission sounds strangely familiar, you’re right--but if things go as usual, it’s poor Shinji who'll get called the slimeball!
