Also known as My Three Sisters Are the Strongest in the World and The Plan to Kidnap the Catgirl Next Door
P.S. I actually wanted to call it Under the Watchful Eyes of My Three Strongest Sisters, I'm Always Ready to Kidnap the Cat Next Door, but that was too long.
After finally being reborn as a newborn in another world, I find that my three sisters dote on me far too much. This won't do. They'll turn me into a good-for-nothing! I need to find a chance to trick the catgirl next door into wandering the world with me.
P.S. A lighthearted slice-of-life story. The fights are so intense they can be ended with one punch. No angst, just healing. Likes and bookmarks count as effective update nudges.
