Its obvious that the author didn't plan ahead of time. He just write whatever hits his mind. Now his in a dilemma because he makes an opponent that shoots laser on her eyes. That's broken in this world's term because its freaking light speed. No matter what kind of stupid reason you give. You will get hit by light! that's IT!!!
and in later volumes Kinji is warming up to Aria so its like an obvious Aria ending. Though Kinji is still tsun tsun to Aria while Aria is dere dere to Kinji. Its funny to see an opposite thing because usually its the girl go tsun tsun but this time its the guy
though its kinda stupid too.
