Please don't be a harem. Love triangle okay. But harem? No. I'm sick and tired of them being in everything that could have been good. Its okay if trash series have harem, but nothing something good.
I've read the Web Novel version of this since it first came out... and I gotta say the plot in the manga is way different. I guess the LN version made a lot of changes. I don't remember this girl and the kuro dog. MC also met sniper girl way way earlier. Him getting the ninja job upgrade wasn't until much later too.
