Sargent, a well-rounded scholar who by all margins should have been the most successful in his first college year instead gave up after a semester, from there more of his usual image of reliability and dedication spiraled into that of a lazy and incapable NEET. Every now and then he would give a sign of his old self: improving his personal fitness, attempting to join the military, and even trying at a technical trade only to give up at the most critical points further cementing his pathetic-ness.
Surely a change of environment might finally motivate him to change especially concerning his new role in life. To save another world at the behest of a goddess.
