Mc has 2 childhood friend, a girl, the other one is a boy. Mc family is the lowest noble. Mc cannot use magic properly because some pact with a deity that has to much power.

In the school the boy who is one of the mc chilhood friend a noble higher than mc always mocked him like useless because mc cannot use magic and sword.

Someday in a class when a teacher teach a lesson how to make a pact with deity. Then he call someone. A girl with shabby clothes come inside a class. Actually she is a stray deity who didnot have a pact almost 10 year. So she didnot have a name. She asking anyone in the class to make a pact with her.

The boy who mc childhood friend stand up and making a scene where he say he want to make a pact with the stray deity. But actually he is lying to her.

Mc cannot stay silent for the boy who mocked her then he went to front. Save the deity and make a pact with her. He named her.

Her clothes make a change to proper one.

Then mc try to his best in the class to promote the deity so anyone can make a pact with her.

Another day a teacher tell the student you will become a knight for a girl scholl next to the magic academy for two year.

Mc ask her childhood friend why she went to magic academy not the girl academy. She say that she want to become someone knight.

In the girl academy mc didnot have anyone who want him to become their knight because of the rumour that mc is useless.

When he look anywhere, mc see three girl vs one girl. Someone in the three summoned a goblin to attack the girl who is alone. Mc see this and run to save her. The girl want to thank to mc so she ask mc name. Mc using his childhood friend name to lie the girl. The girl is actually an earl daughter who mc childhood friend (girl) want to be her knight.

In the hall girl academy that girl who was saved by mc come in.

Mc childhood friend (girl) and some boy ( top rank in class) went to her say that they want to be her knight. But she want to choose someone. When she call a name (fake) l, mc childhood friend (boy) wae happy and run to her. But she asked who are you? Then she know that she has been tricked. So she speak she want a someone with black hair and idiotic face to become her knight. All people eyes went to see mc.

Mc try the last way to save himself. Ask the deity to save him with lying that he was choosen to be the deity knight.

The girl ask the deity from which class, but the deity say the wrong answer.

The girl ask mc again to become her knight. Mc who cannot run then accepted her.
