転生剣豪ズバババァーン

The tale of the strongest old man's reincarnation begins with a powerful tag-team! A single undefeated swordsman at the age of 88 was about to reach the end of his life. What the aging swordsman aimed for was—the "Truth of the Sword." However, it slipped through his fingers, his vision went pitch black, and he fell into darkness. When he next opened his eyes, there was light and—a pair of hills (breasts)! The second life of the strongest swordsman begins now!!
