The Invincible Reincarnated Ponkotsu 5

[Tragic News] My childhood friend is so clumsy, even in another world... She's entirely hopeless, but even after she reincarnated into another world, she was even more incompetent... This might be the most dangerous Reincarnated Into Another World manga out there! All seven of the Seven Braves have finally gathered! But as the shadow of death looms over our heroes, Sota sacrifices his life, Kana’s chest gets petrified, and Sanae-chan has undergone some kind of transfiguration?! [The truth of the world is finally coming to light?! The Ponkotsu Isekai Story is finally reaching its end!]
