Oshinobi Sensei [English, Upscaled], by Hirama Hirokazu
FYI, I upscaled the images of this release, from their original 1024 px high (fucking too small: that made us miss on all the delicious juiciness), to 1600 px (still small, but larger than that and it started looking bad, upscaling is not magic, artefacts appear and I can’t correct them Harry Potter style, I went with the typical unsharp mask.)
We’ve got a pretty pleasant release here, about a highschooler whose family has always been protected by a lineage of ninjas, and the ninja currently following him is a big-breasted adorable cutie. You can safely infer the rest, and I’ll let you attempt to guess which ninjutsu techniques will be put to use
Thanks a lot to Raknnkar and Supershanko, from Raknnkarscans, it was a fine release, I’m glad I can share it with everyone
By the same artist, I also share Osananajimi No Otoshikata, Kamisama No Bangohan and Nurenatsu.

“… which ninjutsu techniques will be put to use.” π€π€π€
The kind that can’t be shown in the mainstream media, without the work being classified as Hentai or Porn. πππ
At least it’s a lot better than THIS:

A ninja… with a headband on which it is written “ninja”. Oh god.
I suppose it’s no more silly than Naruto wearing bright hunter orange, but yeah, that’s pretty bad!
Fu-Fu-Fu … it gets more mind-blowing, like THIS for example:

Ninja teacher, sounds like a failed ABC sitcom from the 90’s.
It was planned as a lead in to Family Matters on Friday nights, but got canned due to a poorly received pilot and the lead actor/producer getting busted in some drug scandal.
Of course it was the first roll of some hot young future starlet who’s career went into a nose dive after a nasty divorce from her leading man husband.
“Jutsu” can just mean “technique”, and in fact, even in Naruto there are more than a few Jutsu that ANYONE could do, such the basics of Taijutsu (i.e. simple martial arts) and the dreaded Thousand Years Death (i.e. a kancho, i.e. ass-poke, which you can OPTIONALLY augment with an infusion of Chakra energy).
I’m not joking when I say this: Im in love with that girl <3
A cute kunoichi with big melons and looks just as good in glasses as well. And is capable of making a strange harem that only consists of herself.
Well, perhaps except for the part about cloning herself to create a harem, your description reminds me of THIS:

Coincidence? ….. NOT!
