(Capcom's primary storyline)
Merah Biji was a member of the Bioterrorism Security Assessment Alliance (BSAA). Formerly a lab technician for the BSAA's Far East branch, she transferred to the Special Operations Unit, earning the admiration of North American SOUs Chris Redfield and Piers Nivans, who she would work alongside of in their investigation of the C-Virus at Marhawa Academy.
Based on BSAA rumours, Merah lost her parents to the Raccoon City Destruction Incident in 1998. Her hatred of bio-weapons led her to joining the BSAA's Far East Branch as a researcher. By around 2009, Merah requested to join the branch's Special Operations Unit. Over her year of training, she met BSAA advisor Doug Wright and Piers Nivans, by which she had become skilled and legendary enough in her own right to spar.
In 2012 she teams up with BSAA North American Branch operatives Chris Redfield and Piers Nivans, to exterminate a group of B.O.W.s in an unspecified place. Later, the agents prepared to contact Prof. Wright.
When Merah tried to contact Doug she was told that he was on a leave. Where she begins to worries is when Doug is still unreachable even at the end of his leave. They decide to move at Bennett University to find out that he moved to the Marhawa Academy with his nephew Ricky Tozawa.
When they arrived at Marhawa Academy, they found the school in a pandemic state and everyone looking for survivors in the school. Chris was the only one to succeed by finding Ricky who briefs them on the situation. Merah was tasked by Chris to find the perpetrator of the incident: Bindi Bergara. Later Chris informed Merah that Doug is dead.
She then proceeds to the cathedral where she finds Bindi whom slaughters the rest of the school survivors. She engages the fight by shooting her in the head and slits her throat thinking that she killed her. She quickly disillusion when Bindi stands back again. She then ignores Chris's order to retreat and disable her radio. She empties her gun on Bindi noticing that it's useless as Bindi's body regenerates, but she also notice that more she hurts her more her body takes time to recover. Then she takes her knife and frenetically slices Bindi until her body wraps in a Chrysalid.
Thinking the fight was over Merah turns back when the chrysalis hatches and let go out a gigantic monster, she tries her best against her but she was no match alone against this form fortunately Piers appears ramming her with the Hummer and crush her against a wall. After Piers neutralizes one more time Bindi by blowing a satchel in the Hummer and by making an additional hole in Bindi's head. Then they can make their way to the underground complex to meet Chris and Ricky despite having many zombies on their way.
When they finally make it to the underground and reunite with the rest of the team they didn't expect that Bindi was still alive when she burst in the room. When she finds Nanan's remains she become infuriated and Merah and her friends know that they had no other choices but to run away.
They manage to reach the helicopter but when they engage the hangar lift Bindi burst again in the room and climb on the elevator, they understand that the fight was inevitable. After a fierce fight Bindi was finally annihilated by a concentrated fire, but the rest was short-lived, when Chris take-off Nanan's rests, which were still alive try to stab Piers with her tentacles, but Merah rams Piers out the way and gets stabbed. After Piers obliterates Nanan, Merah's last words were to ask Chris a world without bioterrorism and to Piers to ask him to take care and watch over Chris, then she dies from her injuries.
