Chrono Kaguya: Please Come, Kaguya

"In that case, Kaguya does it again!" Hearing Iroha's singing, the moon girl Kaguya remembered everything she had with Iroha. Kaguya, who completed the work at the speed of light and created a clone, wanted to return to the earth, but too much time passed, and Iroha has become an old woman! Fortunately, lunar technology can travel through time and space in a snap. But when he was about to arrive, he bumped into a medium-sized stone, which caused a shift in the time he traveled through. So... Two months! Kaguya actually traveled to two months before Iroha picked up little Kaguya!
