I forgot the name of 2 manga and it is driving me crazy. If someone could help me I would be grateful.

What I remember:

First Manga:
Modern setting. Some people can either turn into legendary weapons and others can use them or they are necessary to summon them (I am not sure which one it was). The father of the MC sends a girl to the MC who is his fiance and also the key so that he can use these weapons. He can wield at the very least Excalibur. It is the first weapon he uses. I think she was sent there in like either a big suitcase or a parcel.

Second Manga:
MC is a human weapon who can create swords out of his hands. There are other living weapons? MC is part in a special squad that sacks these living weapons when they run around harming people. He also has like super mode where he gets like 3 or 4 screws on his shoulder and every time he uses 1 slash in super mode the screw retracts but it is insanely strong. He is like the master piece of this one scientist. Later on they find a android girl or something?

I am sorry if this is not very useful but it is all I can remember.

Second one might be Hitogatana

Did u already look it up under the Categories "Legendary Sword"? There aren´t so many - prob. there rings a bell if u read the name?

I think i only know one Manga with humans changing into wapons -> Soul Eater, but the rest of ur description doesn´t fit at all ^^"

Thank you very much both of you.

The first is Legend Hustle which I found with Categories "Legendary Sword". Did not know that was a thing and looked for different categories before.

And the second one certainly is Hitogatana.

I apparently always looked for the wrong Tags also it seems like they are a bit different to what I explained ^^
