I believe the 아니메 should have followed the manga's storyline for the following reasons:
1.The Manga's story is amazing.
2.It would make the show 더 많이 popular.
3.Tskune becomes badass and is able to fight monsters himself.
4.The story wouldn't show panties every 5 seconds.
5. The show would be longer and that would = 더 많이 episodes for people to enjoy.
6.A remake would make people who haven't read the 망가 find out 더 많이 things about Moka and her family. Adding those details would make the story 더 많이 interesting.
7.The fights would be 냉각기 cause Tskune and every one else fights like 10 times 더 많이 and they don't always need Moka's help
8. Tskune himself goes through and interesting evolution through out the series where he goes from being a wimpy average high schooler to an awesome Character who is able to protect the ones he cares about and 당신 learn alot 더 많이 about him like what girl he really wants to be with(no spoilers):).
9. Mizore(yes to all 당신 mizore 팬 당신 also get to learn ALOT 더 많이 about her as well) but there is one part in the 망가 where some stuff happens that the mizore 팬 would love.(no spoilers of course :P)
10. We all want a new season/remake anyways and we'd probably all buy when it came out for sale so there is money to be made in that as well so it would be good for Gonzo to do that for its 팬 :3
11. In the end of one of the 망가 volumes they have lease little short things and in one of them Yukari's mom try's to blow up Yokia academy because no one ever notices her ever so she thinks if she blows up the school she'll be notice(luckily Yukari stops her) but I thought it was funny that she actually wanted to be noticed so it added a bit of story to her too.
