Summon
Summons
noun, verbal noun, の adjective
If you try to call upon someone by screaming for them, you're probably trying to summon them. It's a little bit more serious than just calling them over casually. Maybe you're summoning someone to court, or summoning a magical creature in a video game. Pretty serious stuff.
