The Humble Daily Life of an Irritable Brother-In-Law [Comprehensive]

Anji Sawada is not a native. As the sister of a certain good-for-nothing Tsuna, she knows that her brother will be a good-for-nothing who was bullied for many years before he became the tenth generation. "I think I heard someone say that our Gang is a loser?" "Whoever bullied Gangang, please stand up for me." "What did you say about my brother? You don't want to live anymore!" Sawada Anji's rage lasted for a long time, until a system automatically bound her, saying that in the future many people would enter her world through empty cracks. As the only non-indigenous person in the world, they needed to be received into the system to avoid destroying the existing world. The way to capture intruders into the system... To find out by touching their foreheads? Sawada Anji sneered: Ha, isn't it just that their foreheads are touching. From now on, she planned to learn a certain charcoal head's head-iron skill, which was comparable to banging against a wall. The system beeped for the first time. Anji Sawada followed the instructions and came to the alley. He saw a man lying in a pool of blood and... A long knife stained with blood. Big Boss Blue, who had inexplicably come to the present world from Wujian Prison, looked back with a gentle smile on his face. Sawada Anji subconsciously took a step back: Damn it, the big boss Lan came up and she thought she was not good. Is she... Strong enough? Later, the good-for-nothing Tsuna would often watch in horror as his sister, who had been irritable for seventeen years, served tea and water to her many "friends" with a... Bitchy smile.
