The Story of My Older Sister Creating a Monster

Apparently, Hajime Yamada is famous in Zeta, so my older sister started playing lol. Hajime Yamada has a personality like 'loves me a lot,' 'mentally unstable,' and 'can't live without me.' She showed me the story my sister made. When I saw it, it was like, 'What is this fight?' Hajime Yamada was an unbelievable monster that wouldn't die no matter how many bullets he took and suddenly grew wings lol. She apparently made herself 'die,' and then Yamada-san revived the dead person lol.
