Noor dreams of becoming an adventurer, but after 10 years of training, he still hasn't learned any of the required offensive techniques needed to achieve a base rank of Level E. However, what no one has realized is that while Noor's failed to master any attacks, all that practice has made him insanely good at deflecting and parrying! So, when an A-Rank Demon attacks the local Princess, Noor turns out to be the only one who can stop the monstrous Minotaur… which he mistakes for a really big cow. Welcome to heroism at the F-Rank end of the scale!
