Yo I'm looking for this manga where an average looking Japanese woman is fused with an alien/kaiju and goes on a rampage. The government steps in and the monster hybrid's head is cut off revealing the woman's head and she regains some control, a battle happens, and she ends up still fused with the monster but her human body is back. The promo materials had her holding monster's head while wearing a black bodysuit. She's nervous and scared for most of the chapters from what I remember. My gratitude is yours for the taking but you'll have to find the sauce first! I left everything I owe in one post! [spoiler:lit] the girl in the manga doesn't have glasses like pic rel but I just used it for attention lol [/spoiler:lit]
