MTL - Dressed Like the Scum In the Ancient Bloody Text A - Chapter 45

An ordinary (?) grandfather, Choi Chuntaek. In an effort to protect his granddaughter, he started the virtual reality game 'Arkstar.'

Then... he accidentally obtained a legendary class?

Kuramoto Daisuke, a freshman in High School was suddenly exposed to someone vanishing in front of him. Turns out he was admitted to a Special Class full of Isekai Heroes that were regularly summoned to Otherworlds since the start of their Middle School. He was told that he was to become their Support to prevent each of the Heroes' fate of dying in the world they were summoned into. Though mediocre, he realized that his ability has a great potential but it needs a lot of hard work on his part.

Unconvinced of being just the Support Character, he vowed to excavate his mediocre ability, all the while supporting the Heroes using it.

And maybe more.

Finding himself in an Last Airbender without an airbender around, a transmigrator waterbender goes on an adventure to stop the worst from happening to him.

“Zhong Nuannuan, your charges have been withdrawn. The courts have declared you innocent and pronounced you not guilty for murder. You can leave prison now. Your family is waiting for you in the waiting room outside.” Zhong Nuannuan was startled. She pushed the female prison guard to the side and ran toward the waiting room. She did not even bother to put on her shoes. If not for the icy feeling she felt at every step of the way reminding her that this was not a dream, Zhong Nuannuan would not have believed that she had resurrected.
As she burst through the doors and saw him again, she knew in her heart, that this time she would get it right. This time she would cherish him properly and hopefully, just hopefully, turn her own fate around.
