Geez her mom is worst parent...

Her mom abandoned and neglected her. It doesn't matter what excuse she has the damage to Kyoko is done and apparent. Ever wonder why Kyoko was so clingy with Sho and a pushover? It's because she was desperate and starved for attention, affection, praise, and love. When you are a parent your kid comes first regardless of whatever excuse you may have. And if you fail to put your kid first and damage them then you've failed. Sho and Kyoko's mom already failed her. It's too late. Kyoko has Moko, Lory, and Ren now so they are unnecessary.
