1. -You can enter a universe one at a time. Traveling between the multiverses at the same time is strictly prohibited.
2. -You can't choose how your incarnation's avatar appearance will be. All of it will be saved in the database so you can utilise each avatar's strengths. Each avatar has a certain peculiar strength.
3. You'll retain every single memory of "Entries" to the world you entered in the past, which includes the skillset and superpowers. Still, some of them can't be used in another world due to certain restrictions.
4. -You can choose to change the name of your avatar to be suitable for certain worlds.
5. -You'll die like other mortals even if you're entering the multiverse. Death means failure; you have to start the mission from scratch until you clear the mission in a different timeline.
6. -You will be responsible for everything that happens to you. Complaining is useless.
7. -You can only choose two of your favourite women from any multiverse. Having more than two wives is strictly forbidden.
8. -Everything you feel in every universe is real. All emotions are set so your entries feel realistic, like real life, to build a high level of immersion. If you feel sadness, your core emotions will also feel the same pain.
9. -Missions can be multi-tangible or unrelated to one another. You can't question the mission. Your only job is to clear the mission, even if imperfect.
10. -You won't be overpowered; only skill mastery and superpowers are your advantages. It is your ability to use them creatively to solve problems that counts for success in your mission.
