Why would he do this..?

You were holding back monsters so that Cloud's team could escape from their clutches since they were cornered

Brutal sounds and attacks were heard, the sounds of you hitting the monsters were heard along with it attacking you

Soon or later the monsters multipled and even worse a bomb. You hated those bomb's for life due to their explosion which inflicts a lot of damage on you

More bomb's came and more explosions you would try to avoid, you were soon attacked some bomb's since you had no choice, though one behind you with low HP exploded without warning causing you to stumble forward in pain

The bomb's with low HP took advantage of this and started to explode inflicting more damage on you

After 4 or 5 more explosions the bomb's came to a pause for about five seconds due to them decreasing and this only gave you time to try to defend

You got in a defensive stance and closed your eyes as a bomb started to explode but when it exploded, you didn't take no damage at all

You slowly opened one eye only to see the one winged angel, Sephiroth. His black wing wrapped around you loosely to block the explosion along with him standing there like the menace he is holding his masamune in his left hand, standing there with no damage taken on him

Sephiroth:"Never thought of using your super speed to run off and catch up with Cloud, the monsters wouldn't be able to catch with you." He stated in a compose way
