Lets Begin a Battle Without the Hero Vol 1

Description:

Akane Kohinata is the perfect main character. She saves hundreds of thousands, brings smiles to people’s faces, and never gives up. However, a climactic battle with the cataclysmic cosmic beasts proves to be her last, and with her final breath, she leaves her legacy in the hands of Tsugumichi Takahashi. The only problem is, he’s a helpless shut-in who doesn’t know the first thing about heroics. Does this nobody really have what it takes to inherit Akane’s will? Project zero to hero is now underway!
