"Just stay here, you've been doing your best for this exam." Yato grabbed Ruth's hand before he could make a run from it and he continued by saying: "Don't let yourself defeat what you have worked for. Besides, our turn is soon to come."
Ruth has been hunting magical beasts for their cores every day and he has also used a large sum of platinum bars to purchase spellbooks and mana cores to hurriedly improve his strength. All of it was done to prove himself as an ace in this very exam.
As soon as Yato's said his words, Ruth finally came to his senses. He thought,
'How could I allow a momentary weakness to ruin my future? I just need to get by this exam and then I will reward myself with ten days of isolation!'
Ruth braced his chest, and turned to stare at Yato gratefully, "I will do my best in the assessment examination. So you better give it yours all too. Show those bullies that you won't stay down no matter what."
