So bc he has someone who loves him, he doesnt have to be alone and struggle, right? That makes sense. Someone below said the Author said on Twitter that hes not gonna get buff. Tbh, it would make sense for him to grow in height as he gets older. As far as buff, I would think he could have maybe a smaller frame, but have a muscular or sculpted body. Thats just me tho. Like if I was the author, thats how I would draw him. Maybe as tall as Gozu, but not as bulky as him. He could easily protect Gozu now even in his smaller form so I guess his body tyoe wouldnt matter.
i don't if it's because of Gozu, but i don't think Ece will grow a single milimeter in the main plot. Like, yes he was big in the original gane and super powerfull buffy man, but in that timeline he was all on his own, so he had to man up and show the world a side of him that would terrify them without doing anything.
