After living life as a corporate lapdog, Arihito is reborn in a fantasy world. Strangely, the class he's assigned is the very ambiguously titled Rearguard. It seems weird, but
Arihito soon figures out that though it isn't flashy, he's gained the ability to
do just about everything in battle, from assisting attacking and defending to
healing! As he begins his new life, he quickly gathers curious companions: his
old supervisor who's younger than he is, a mysterious demi-human mercenary girl,
and a gorgeous high-level swordswoman. With this bevvy of interesting ladies in
his party, his journey as the greatest supporter that's ever
lived!
