Hi! I'm glad to hear that you liked the update!
- It’s not possible yet. We are planning a "final stage" for the NTR progression that starts after a certain Love level. In this stage, as the MC gets closer to Akira, Mike loses his influence and vice-versa. The one who reaches max influence first wins her heart (at least, that is how we have it planned).
- Mike is intentionally unbeatable for now, mostly to motivate the player to get revenge on him. I'm happy to hear that it's working, haha! The tattoo will disappear if/when you beat Mike in the final stage I described earlier. If you don't like the tattoo, it's best to avoid fighting him for now.
Huge thanks for the feedback!
