The trouble with that method is you need a setup involving Erina's LSD to actually get out of the Magatsu's range of vision before it mobilizes. And I'm not sure if the ten-second activation point for 0-second LSDs (where LSDs that activate at 0 seconds actually activate at 10 seconds) was instituted in GE2 1.4 or in GE2RB. Basically you equip Erina's LSD and make a break for the right/bottommost hallway as soon as you can. Jump down and start sprinting literally as soon as the battle starts. Hell, hold down forward so you start running at the absolute earliest possible opportunity. And even then, it's not 100% guaranteed to work.

My advice would be to just start wailing on the Magatsu and just tough it out when the Sekhmet and Fierce Kongou show up. When any of them flee (even the Magatsu), LET THEM GO and focus on the one(s) that remain. Due to the shape of the Scarred Barricade, there's a next to 0% chance that they'll notice you unless you get up in their face while they're eating.

When the Magatsu uses Killing Stone, get out of the way as soon as you can and use health boosters to regain your max HP limit. STAY THERE AND LET THE MAGATSU COME TO YOU.

Alternatively... the Magatsu only uses Killing Stone when it becomes enraged. When you knock it down, wail on it for a little bit, then bring up your items menu. When it gets up, wait until it stands up all the way and IMMEDIATELY use a stun grenade. You'll actually cancel out its rage mode and prevent the use of Killing Stone. Of course, it CAN still go into rage mode without being Downed, so watch out.
