I enjoy cybersecurity.

I primarily deal with the sales of security products. Recently, I've taken a particular interest in social engineering.

I love infrastructure. I live in VRChat. I work on infrastructure development using Kubernetes and Terraform, and I'm also involved in SRE (Site Reliability Engineering).

I like both making and breaking stuff. I do random stuff; from binary analysis to forensics and recon.

I am a security instructor and also develop tools related to penetration testing. In the past, I have presented at BlackHat Asia Arsenal, SECCON YOROZU, and AVTokyo HIVE. I am also CISSP certified.

We started researching security issues in online games last year to build the community with Japanese game companies. At NCFTA Disruption 23, we shared our findings on Minecraft MOD and received some positive feedback.

I spend days of thinking of that achieving cybersecurity is really difficult. I think it would be impossible to do it alone, so I would be happy if the defenders could cooperate with trusted friends. I'm not growing well like a sleeping egg. First spep:　Wake up and start working!
