This isn’t something that boys like, is it!! A juku teacher said that college students’ sexual desires are out of control… I will absolutely not click on this! GAMES Why!!? It’s lewd!! Isn’t this a world of adult-oriented doujin RPGs!! I can’t stop this, it’s terrible, please help me! Going back to juku… (Oh no, with this body, being a sister is impossible, right?

1: Japan Otaku ReviewsYeahx13

It was a good story… to be continued!?

2: Japan Otaku ReviewsYeahx6

Is it the one I drew in a one-shot before?

Will it be serialized alongside Time-sensei?

3: Japan Otaku Reviews

I would read erotic manga.

4: Japan Otaku ReviewsYeahx7

>>3

It seems that there are erotic pinch scenarios that are paid and also have bad endings.

I haven’t read it yet because it was paid.

5: Japan Otaku ReviewsYeahx8

Do you think all the readers are doing Zico?

I understand, but…

6: Japan Otaku ReviewsYeahx2

Treading the line with risqué themes is just the best…

7: Japan Otaku ReviewsYeahx5

It was a good story… BAD END edition!?

8: Japan Otaku ReviewsYeahx13

The erotic events for the bad ending are paid… what a good business they’re running!

9: Japan Otaku Reviews

One-shot version

Paid bonus edition

https://youngchampion.jp/series/5208125585498

10: Japan Otaku ReviewsYeahx11

Aren’t you hopping between publishers a bit too much!?

14: Japan Otaku ReviewsYeahx2

>>10

I had an image of someone from Shueisha, though.

This new series is a champion.

The current series was also in Gorak.

Goraku, huh…

16: Japan Otaku ReviewsYeahx3

>>14

I was drawing in Good Afternoon (Kodansha) too!

18: Japan Otaku ReviewsYeahx1

>>14

Are you serious?

What a drastic downfall in life.

11: Japan Otaku ReviewsYeahx12

When I think about it calmly, it’s a bit frightening to visualize how my level of promiscuity could increase due to some stimulus…

12: Japan Otaku ReviewsYeahx4

I’ll wait for the comics.

13: Japan Otaku Reviews

Hmm, that’s naughty…

15: Japan Otaku ReviewsYeahx35

A bad ending for a fee? That’s already Fantia!

17: Japan Otaku ReviewsYeahx17

Don’t sell in an unbelievable way!

19: Japan Otaku ReviewsYeahx6

It sounds good to say it’s a new business model, but…

You could say they’ve pulled off some shady business!

So, will this bonus page be included in the paperback edition?

20: Japan Otaku ReviewsYeahx2

The self-destruct button on Zico is cool, isn’t it?

21: Japan Otaku Reviews

How erotic is it?

22: Japan Otaku ReviewsYeahx2

Complete with a bad ending, as expected…

23: Japan Otaku ReviewsYeahx3

If I can pay to see the contents of the author’s desk drawer.

I will pay money.

24: Japan Otaku ReviewsYeahx1

The kindness that feels as if my heart has been read.

25: Japan Otaku ReviewsYeahx7

This is Zico’s world, isn’t it…?

26: Japan Otaku Reviews

If you can obtain cheat items or cheat codes, there is a possibility you can dominate.

28: Japan Otaku ReviewsYeahx2

If it’s only knowledge from Narou, this would be damn boring, right?

29: Japan Otaku ReviewsYeahx1

It had finished serialization in Goraku.

47: Japan Otaku Reviews

>>29

It’s continuing normally.

It seems to be selling quite well.

30: Japan Otaku ReviewsYeahx4

As expected, the first playthrough should be a virgin clear.

31: Japan Otaku Reviews

Umichan’s erotic drawings don’t really resonate with my penis, but the situation of being hypnotized and made to bathe together is good.

32: Japan Otaku ReviewsYeahx1

Wait a minute, I’m really interested in this big-chested boy.

34: Japan Otaku Reviews

I bought both BAD2 episodes, but they are short at 5 pages and have low practicality.

At this point, it seems that Dr. Tokime is still ahead.

35: Japan Otaku Reviews

Hmm, it was a bit ambiguous.

36: Japan Otaku Reviews

I was reminded while reading that the degree of lewdness can sometimes be treated like a desire gauge.

37: Japan Otaku ReviewsYeahx2

Well, since Sensei has become quite straightforward in his depictions…

It’s deceitful…

38: Japan Otaku ReviewsYeahx6

Let me know when the paperback comes out.

39: Japan Otaku Reviews

Isn’t it too rough to have the event conditions with the townspeople met just by receiving a single hit?

40: Japan Otaku ReviewsYeahx4

>>39

I think it’s partly to blame for ignoring the original event and challenging a high-level boss.

41: Japan Otaku Reviews

Well, if I can be brought down by masturbation, then that’s fine…

At this rate, it seems that I won’t gain any experience points and will remain at level 1 indefinitely.

42: Japan Otaku ReviewsYeahx3

Selling a bad ending version for a fee is really smart…

43: Japan Otaku ReviewsYeahx3

The way to draw breasts has become a bit tricky…

44: Japan Otaku ReviewsYeahx1

If you’re going to draw erotic manga, then do it as doujinshi and sell it.

45: Japan Otaku Reviews

Maybe this will get buried if it’s professional.

49: Japan Otaku Reviews

>>45

Is it at the level of doujin?

54: Japan Otaku ReviewsYeahx5

>>49

It’s more of a customer base issue.

46: Japan Otaku Reviews

It continues with this setting…

48: Japan Otaku Reviews

The guy from Golaku seems to be quite popular.

50: Japan Otaku Reviews

Did I say it might be 10 yen during the Fanza sale?

51: Japan Otaku Reviews

Umichang! It’s been a while since I last saw you.

52: Japan Otaku ReviewsYeahx3

Is it a girl?

I hope that many cute girls will appear from now on because that was lewd.

It’s not that the protagonist lacks charm, but…

53: Japan Otaku Reviews

It might be revolutionary to prepare two routes even in manga.

It’s a benefit for everyone.

55: Japan Otaku Reviews

I don’t know how erotic the paid version is, but it’s nice that the free version is plenty erotic as well.

If I’m just going to pay 70 cents, I might as well read the porter’s side.

56: Japan Otaku Reviews

I’m happy because I liked one-shot stories.

57: Japan Otaku Reviews

Charging for a bad ending is clever…

58: Japan Otaku Reviews

It’s really thoughtful to have a bad ending.

59: Japan Otaku ReviewsYeahx4

I loved the prince-like transformation heroine from the previous work.

60: Japan Otaku Reviews

The shape of the breasts seems to reflect personal preferences or is it tailored to the audience that plays this kind of game?

61: Japan Otaku ReviewsYeahx1

The blonde big-bust short-haired girl from the first episode has a good character design, but I guess she probably won’t have any more appearances.

92: Japan Otaku ReviewsYeahx1

>>61

You might be summoned here.

62: Japan Otaku Reviews

When I compared the readings, the complete story of the black bread turned into white bread…

63: Japan Otaku Reviews

I thought it was one of those where the nipples wouldn’t show, but I was surprised when they appeared normally in the second half.

64: Japan Otaku ReviewsYeahx1

The self-destruct switch is an incredibly powerful weapon…

65: Japan Otaku Reviews

>>64

But it seems like it’s just a one-time thing.

66: Japan Otaku ReviewsYeahx3

It might be better if it doesn’t continue, right?!!

How can we make this even more exciting!?

67: Japan Otaku ReviewsYeahx4

In erotic doujin games, suicide items can be used multiple times to view defeat erotic scenes of your character.

69: Japan Otaku Reviews

>>67

If you push yourself, it’s not like you forced it onto someone else.

Isn’t the self-destruct button going to become the opponent’s self-destruct button?

76: Japan Otaku ReviewsYeahx1

>>67

It’s already stated in episode 2 that it can’t be used anymore, so it probably doesn’t apply to this work.

Which way will Saho-chan’s tomorrow go?

68: Japan Otaku Reviews

Or they are selling it at a throwaway price.

70: Japan Otaku Reviews

You’re cute!

71: Japan Otaku Reviews

Umichang and Midoriyama started new series at the same time.

What answer can be derived from here?

73: Japan Otaku Reviews

>>71

Are you drawing new works that won’t continue?

72: Japan Otaku Reviews

I’ve been thinking about this since Marine Day, but the way the story is being told to show the developments I want to see feels like it’s skipping several steps, and it’s concerning.

74: Japan Otaku Reviews

Did I mess up the proportions of the drawing and make it look worse?

75: Japan Otaku ReviewsYeahx4

The girl’s hobbies are quite distant from my own, but I kind of like talking about them.

77: Japan Otaku ReviewsYeahx1

Your face looks too much like Sensei Tokime.

78: Japan Otaku Reviews

You went to Golaku!?

87: Japan Otaku Reviews

>>78

Mr. Ji has been serializing for quite a while!

80: Japan Otaku Reviews

I see, a bad end… that’s a relief…

81: Japan Otaku Reviews

I think the city of Ketsunana has a high level of Jiko.

82: Japan Otaku ReviewsYeahx1

The door illustration for episode 2 was in a Hunter x Hunter style and it was no good.

83: Japan Otaku Reviews

Every time I use the guide ring, it feels a bit like a hunter.

84: Japan Otaku Reviews

The way the death is confirmed with a guide ring feels kind of nice, like a finger gun.

85: Japan Otaku ReviewsYeahx3

If you lure them in with a free main story and guide them to a paid bad ending…

What a wicked way to do things.

I don’t dislike it.

86: Japan Otaku Reviews

The girl is cute, but I wish she had a slightly bigger pair of beautiful breasts… The mob character who was kidnapped in the flashback and episode 2 has bigger breasts…

88: Japan Otaku Reviews

>>86

I’m always messing up the settings for the heroine.

89: Japan Otaku Reviews

>>88

Mr. Toki is a pervert and his erotic fantasies are terrible, but he is a good teacher…

90: Japan Otaku ReviewsYeahx2

Was that the one who was doing various one-shots?

93: Japan Otaku Reviews

It would be great if my friend’s kid came over here, made up, and had some steamy experiences!

94: Japan Otaku Reviews

Unlike the teacher, you’re younger, so you should lean towards a more cute look with your gaze…

95: Japan Otaku Reviews

Has the drawing become a bit rougher compared to the past?

I wonder if it’s like this lately.

96: Japan Otaku Reviews

Yan-chan’s skills in isekai are quite high.

It might be that the editing is working hard on some works where the contract allows for adaptations of the original work, and changes to the story are being made.

97: Japan Otaku Reviews

I really like friendship stories about lower-caste girls, like in Ghost World…

98: Japan Otaku Reviews

Is it hell that a bad ending costs money…?

99: Japan Otaku Reviews

Because I have a boyish taste…

100: Japan Otaku ReviewsYeahx3

I really like the character design, but I can’t say anything without trying to read the bad parts.

101: Japan Otaku Reviews

Even though she’s beautiful, I wonder if she ended up alone because her expressions tend to be quite off-putting?

102: Japan Otaku Reviews

I’m concerned about the feeling that my breasts are hanging down or positioned lower.

It has that kind of feeling, even in the pictures of girls wearing clothes.

103: Japan Otaku Reviews

Isn’t he someone who likes girls with that kind of body type?

104: Japan Otaku Reviews

I rented the BADEND version with a donation mindset and laughed at the textless differences.

105: Japan Otaku ReviewsYeahx7

>>104

You’re totally that kind of person now!!

106: Japan Otaku Reviews

Wouldn’t it have been more profitable to sell it on dlsite?
