what you could get would be a deity title update, nor does the title make sense, it looks more like a war deity than a delivery one, the first world fights a beast, in the second against demons, in the third nothing, in the fourth he fights a dragon and in the fifth he joins the war with nobunaga, god of deliveries makes no sense
The story is going good..And for next arc I would recommend you to seal all his powers and train him for 1-2 y(with time fluctuations) like normal human to strengthen his mentality and body like using a **Tower that trains you to build best Physical condition by using Martial Arts and uses your deepest fear to strengthen your beliefs**. Hope you use this concept because this training basically help him to reach pinnacle of normal humanity without any other anime techniques..
Thx for the chapter. One of the Fairy Tail magics would be cool or a proficiency in some type of crafting. Maybe a bonding skill that he can use with his lovers that allows for the exchange of skils/bloodlines/thoughts/mana/etc. depending on the level of the bond/affection. A scientific company for his sister possibly? Or a contraceptive ability. Empathetic ability so he starts accepting the feelings of others.
