   Summary

   Growling sounds from behind him and Izuku closes his eyes briefly, grimacing, as he opens them up and gauges Kacchan’s reaction.

   “I don’t know who you think you are, asshole, but leave my daddy alone,” Ren snaps his teeth at Kacchan. Izuku is horrified.

   One: where the hell did he learn that word.
   Two: oh fuck oh fuck oh fuck

   “Ren,” Izuku looks down at his son.

   “Yeah, who are you? Don’t be mean to my daddy,” Hotaru stomps her foot, staring down the shocked alpha.

   Kaito shuffles forward, growling, but a little shy, “daddy, we- we’ll beat up that mean alpha for you.” He looks over at Kacchan, shaking as he steps in front of Izuku and his siblings, “we-we’re alpha’s too, we’ll beat you up.”

   Hotaru steps forward and holds her brother’s hand, growling and glaring at Kacchan. Honestly if it wasn’t Izuku’s worst nightmare coming true, he’d think it funny to see his childhood best friend faced with his pups treating him the same way he treats others.

   Kacchan stares at the three of them in shock and awe. He freezes when he gets to Ren and looks up at Izuku in disbelief before looking back down at the pups.

   “Deku. How old are they?” Izuku is shaking, tears pricking his eyes.
