7fates Chakho Vol. 2 (comic)

Under Haru’s tutelage, Zeha’s skills grow by leaps and bounds. But when his sword breaks from the strain of fighting the Beom, he goes looking for a replacement in the last place he expected—a history museum! Following Haru’s advice, he picks up a rusty relic blade and finds that it suits him perfectly, as if it has always belonged to him…Even with a powerful new weapon, the odds are stacked against Zeha, as the Beom’s onslaught grows into a full-on invasion.
