Be Prepared, Be Smart, or Be Lucky (予習・復習・不勉強) is the thirteenth episode of The Irresponsible Captain Tylor. It aired on April 19th, 1993 in Japan.
The Raalgon Admiral Donan wants revenge on Captain Tylor. He attacks the Soyokaze until it is so damaged that it can't use its weapons or deploy fighters. With no other choice, the Soyokaze warps repeatedly until it is next to a large star. Donan fires at them again, but the star's gravity draws in the lasers instead. The explosion that ensues destroys Donan's ship.
